Jeff, I think you want to use EDIT ITEM.
$objName:=OBJECT Get name(Object current) // will be the name of the listbox object even if called from a column/array $row:=listbox_get_rowcolumn ($objName;->$column;->$objPtr) // method gets the row and ptr to the column & column object If(Not( code to test the input is ok)) EDIT ITEM($objPtr->;$row) End if This works in the listbox object or the array within the listbox.
