Hello,

I have two textboxes and one label in a form. I am looking to display the sum of both textboxes in the label on "real time", in fact to execute the sum when I lost the focus of one of the textboxes.

For example at the beginning everything is in ceros. if I type "5" in the textbox a and press [TAB] (or click outside the textbox a) the label should be "5" and if I type "2"...
