List box operation in a sub form

[hawkingsright]

hello! i am having trouble with a list box in my sub form. i am able to select an item from it (items are linked to a table), but when i try to use it again on the next line, it will not select a new item, instead showing only the previously selected item from the line line above. how can i correct this? the desired outcome is to select an inventory item from the list and have the cost dumped in another column. this works on the first entry, but not on the next line. it always shows the item selected for the first entry, no matter what item you click on.:banghead:

much thanks!
