Hi.. Thanks alot for finding time to help a beginner like me. What I am trying to do is validate the input i get. I just want to take numbers and numbers only. So if the input is 23+1 or 2/3 or 9-0 or 7/0 , I want to find it using reg exp. I know there are other ways to do this... but i thought i will try this as i need to learn reg exp. I tried \D+ , \W+, and \D+|\W+ .. Thanks once again...
