Conflict of intrest

[dennisbowman]

I need a form that has One comboboxe and a listbox. The Comobox holds a list of students and a list box that only displays only the teacher that havent taught the student.
for example if i have 4 employee one name don, and don had a lesson with a student,when that student is selected all the employees are listed in the listbox except don.

Thanks in advance
Dennis

You can either use the Not In() or Not Exist in your WHERE clause.

for the listbox,
you can first create a query that will list all possible Student + Teacher combination (see qryCrossJoinTeachersStudents query).
then create a query that will list teachers not already taught the student (qryLstSource, this is the row source of the listbox).
see Form1.
