You could keep track of what has been selected by creating an array of strings (max=maximum # of combo boxes) and remove the courses selected from the other combo boxes (once chosen) to prevent the other combo boxes from chosing a course more than once...
HELP (again) ....
I have 28 comboboxes (filled with courses) on a form ... all being populated by an SQL and an additem. All the boxes have the same name CBB1 and I'm using the index to reference them.
I need to be able to give an error, if a course has already been selected in a previous combo.
is this possible?
Thanks for any suggetsions :)
