Thank you, Tom. The combo-boxes are controls, not forms. Your code
worked very well, with the exception of one minor detail. The code
checks all sheets in the workbook, what if I needed it to only
reference one sheet? Is there a way to specify the worksheet? I will
try to solve this, but if you have the answer, I would greatly
appreciate it.

Thanks again for your help!

NicB.
