Combo to Combo problem **Resolved**

[GlenW]

Thanks jdc2000 your solution was perfect.

Please bear with me!


I've got 3 combos.
Combo1 gets a list of experiments from a db.
When an experiment is selected in combo1, combo2 gets filled with the possible leg numbers of that experiment, combo3 with the possible descriptions.
A leg matches to a description. Together they are unique.
So the exact leg - description combination can be got by either
selecting from combo2 or combo3. With me so far?
Now, if I select the leg, I want the description to be automatically shown in combo3 and vice versa.
But, heres the problem, if the description is chosen I want leg to be auto shown.
This gets me into an infinite loop type thing. (top english!)
Combo2 tells combo3 what to show but then combo3 tells combo2 what to show so combo2 tells combo3...... etc. etc.

Any ideas.
