Cheers! And yes you're right, my comprehension of regex (even though a simple expression) is now better for it! Yep I sat there until the wee hours testing every permutation of the string as I could think of and the pattern works great. I shall just stream line it by doing something with the \d instead of [0-9].
In this particular context, designed through vb.net I have complete control over what chars/ints are allowed in the text area via KeyPressed event.
Excellent, and again, thanks. I did tweet you with a thanks and WebmasterWorld tag ;)
