title: trying to validate user input when exiting textbox in VB
body: <p>I would think this problem is so simple and basic , I just can't get anything to work. I just want to validate user input and I can never get the validation rules to fire only when I want .  I've tried using got focus , lost focus , leave , and validating .  Some of those fire when the forms loaded some trigger when other fields look up .  There have to be an easy way I hope you can understand and can help. thanks</p>
