The lists are used on the Multi Row screen. To see/use them, open the input
screen for the input set for which you defined the list. On the multi-row
screen, double-click on an account to which you wish to add line items. The
green "difference from total" line will appear. Click the blue Plus button
to add a new line item. The blank line item row will appear between the
account row and the "difference" row and in the ID field will have a zoom
button (the elipsis button to the right-hand side of the cell). Click that
and it will pop up the list you defined.
I hope this helps.
