OK, I'm stumped. I basically have a textbox, call it txtNewValue in the form footer that I would like updating after the user updates a bound textbox in the detail section and after the user clicks a save button . I have straightforward math for txtNewValue calculation, but now since it's not updating correctly, I've assigned values to TempVar variable and made txtNewValue bound to the TempVar variable. I noticed that in real time, the txtNewValue is not updating when the user clicks the save button. However, when I step through the codes, upon the me.form.requery, the value is updated. If I remove the break point and run it, txtNewValue does not get updated. Even if close down the form and relaunch it, txtNewValue is not updated. What's going on?
