validation help

-1

Sep 25th, 2009

I have a text box in a form that is validated to accept a value called ds01 but i also want the textbox to be allowed to accept empty spaces that is if nothing is entered in the textbox. The problem is that it does not accept anything other than ds01. Thanx in advance for your help. This is my script
