I use a lookupcombo to get 'list_number' info. from a table.
I also have my contacts showing (name,surname)
in a grid (that gets data from a queery)..
So before I do anything I would like to check if a list_number allready exists
for the selected contact in the grid.
(a check would be on the exit event of the lookupcombo using a queery just for that purpose)
