Hi Jimmy,

>I want to make two comboboxes sum to a textbox on upclick. the problem? this procedure only seems to work when i put the code '? combo1+combo2' in the click event of the textbox. unfortunately, the output doesn't go to the textbox, but is justified to the left of the screen. what am i doing wrong?

Do:

This.Value = YourComboSumsHere
This.Refresh

Does this help?
