Selected item on dynamic panel
I am writing a simple math program. I have a button for ADD, SUBTRACTION, etc. Click on a button and I create a dynamic panel for each area. On the new panel I have a combo box to select a starting point. I want to display that selection in a text box to create the upper number of a math problem. The selected item always comes up empty. How do I get the selected value into a variable so I can use it in the program?
