>When I enter data in the first textbox and hit enter key, it goes directly to the OK button ignoring the second textbox, tabs are ok and the controlsources of the 2 textboxes are ok, and if I enter data in the first and push tab key or cursordown key goes to the second textbox.

Does the OK button get fired, or just the focus? If Enter is pressed on a form with a command button with the Default Property set to .T., it will fire the click of that button.
