Or I can get you started by saying that I think you're regular expression is saying "beginning with anything, then exactly 3 numbers, then anything, then exactly 3 numbers, then anything, then ending in exactly 4 numbers". Changing a {3} to {3,4} would mean "match 3-4 occurences of what's to the left". Hopefully that will get you started, if you post some other numbers you want to pass validation we can be of more assistance. regex are very powerful and I recommend you add them to your training. That said, people enter #s in many different formats and sometimes it's necessary to enter a # like "011-817-972-1086 x103" or "817-972-1086, 1, 3, 12" if you're dealing with business numbers with extensions or automated systems that have to be traversed. So you may be better off not validating the phone #. YMMV. -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/
