I have a combo box on a form that I want to apply a filter to my form. The combo box is populated with choices such as "Round 1", "Round 2", etc. "Round 1" and "Round 2" are the PeriodID for the records on the form. I want the user to be able to select the Round from the combo box and have the form filter to show only those records with a matching PeriodID. How would I write this code for the filter? Thanks for your time and help!
