What am I missing? I am trying to populate options for one combo box based off of another. I have been reading through these threads to figure out what I am missing but can't seem to get it. You will see that based on the "Action" combo box, I want the "Place" combo box to automatically populate with the specific criteria in my Action table. It almost seems that I am missing what combo box my "Place" points to. I feel I covered that in my Row Source for that field but apparently not.
