Key Focus property is not working for control

[tomp93]

I want to create a vi for checking serial no which should be like 'ESN954009'. If anyone enter it wrong, it should display a command prompt which tells them to correct it. Here in my program a command prompt is displaying always even though 'ok' is pressed.
