19- Increments list: If the increment is 0 (i.e. undefined) a "?" is displayed under the increment label (above the list) and the list of default increments is displayed in the increment list.
Note: the values displayed in this list can be changed. To add an increment in the list, type the value in the input field( # 17 ) then press the Enter key. To remove an increment in the list, type the value in the input field( # 17 ) then hold the Ctrl key then press the Delete key. Also the list can be modified by editing file applet.htm of directory auctioneer.

Clicking an amount in this list generates different actions depending on the current state of the "Replace Inc." check box:

"Replace Inc." NOT checked:

Again, clicking an amount in the list box generates different actions depending on the high bid, asking and increment values.

case 1: high bid = 0, asking = 0, increment = 0
The increment list contains all the values from file applet.htm: 1, 2, 2.5, 5, 10, 12.50, 20, 25, 50, 100, etc.
Clicking 25 will result in setting the asking amount to 25, leaving the high bid and the increment unchanged. This leads to case 2 below.

case 2: high bid = 0, asking = 25, increment = 0
The increment list contains all the values from file applet.htm: 1, 2, 2.5, 5, 10, 12.50, 20, 25, 50, 100, etc.
Clicking 50 in the list will place an On Site bid equals to the asking amount (i.e. 25), will increment the asking amount by 50 (setting it to 75) and will set the increment value to 50.
The net result will be: high bid = 25, asking = 75, increment = 50. The asking list now displays: 75, 125, 175, 225, etc. and the list of  increments now displays: 1-, 2-, -2.50, 5-, 10-, -12.50, 20-, 25-. The "-" beside an amount means that the asking will be decremented if this increment amount is clicked. This leads to case 3 below.

case 3: high bid = 25, asking = 75, increment = 50
The increment list now contains: 1-, 2-, 2.50, 5-, 10-, 12.50, 20-, 25-.
Clicking 20- will leave the high bid amount unchanged, will decrement the asking amount by 20 (setting it to 55) and  will set the increment to 20.
The net result will be: high bid = 25, asking = 55, increment = 20. The asking list now displays: 55, 75, 95, 115, etc. and the list of  increments now displays: 1-, 2-, 2.50, 5-, 10-, 12.50, 20-, 25-.

case 4: high bid = 0, asking = 0, increment = 25
The increment list contains all the values from file applet.htm: 1, 2, 5, 10, 20, 25, 50, 100, etc.
Clicking 100 will result in setting the asking amount to 100, leaving the high bid and the increment unchanged.
The net result will be: high bid = 0, asking = 100, increment = 25. The asking list now displays: 100, 125, 150, 175, etc. and the list of  increments now displays: 1-, 2-, 5-, 10-, 20-, 25-, 50-.
 

The list of all values from file applet.htm is displayed. Clicking an amount in the list (or specifying one in the Input field above the "Increment list"), will set the increment value to the clicked amount, leaving the high bid amount and the asking amount unchanged.

case 1: the asking amount has not been specified yet (i.e. the lot has been created with a blank asking amount). In this case the list contains only one entry, a question mark ("?"), clicking it does nothing.

case 2: the current increment value is 0 (i.e. "?") and an asking amount has been specified, either when the lot was created or using the input field below the list. In this case the list contains only one value, the current asking amount. Clicking it, will make a bid of that amount, will set the new asking amount to twice that amount and will set the increment to that amount.
For example if the list contains 500 only and the current increment is 0, clicking the 500 will result in the following new values: high bid = 500, asking = 1000 and increment = 500. 

case 3: both the increment and asking amounts are greater than zero. In this case the list will display the current asking amount followed by a sequence of amounts, each being greater than the preceeding one by one increment value.
For example, if the first amount in the asking list is 9975 and the increment is 25, the list will contain the following values: 9975, 10000, 10025, 10050, 10075, 10100 ...
Clicking any of these values will make an On Site bid equal to the clicked amount. For example, if you click 10025, this will generate an On Site bid of 10025, the new asking amount will be set to 10050 and the increment will remain unchanged. The new displayed values will then be: 10050, 10075, 10100, 10125, 10150, ...

This list is useful when the pace of the auction is very fast. Consider the case where 5 bidders raise their hands one after the other and the last one is for the 10075 asking amount. You don't need to click the On Site Bid button 5 times, simply click on 10075.  10075 will become the new high bid and the new asking amount will be set to 10100.

23- Checking this check box will force the use of a preset table of increments. Controls related to increments settings will be hidden. 

Multi-Buyers checked box could be applicable for the following: a lot or a group of lots with choices in numerical order that have 1 as quantity for each lot.




In the event that the winner do not choose the whole quantity, potential buyers that wish to buy at the same price could send their chosen quantity while the winner is choosing. All offers related to the lot(s) that meet the winning bid will be considered(excluding the offers of the winner). See the image below that show the result of the action generated by clicking the "Choose" button.
