I don't think you want a - before the a-z 2. You have ()s around only the stuff *AFTER* the first character. So you are losing that stuff in the ()s to be saved in the third argument you're not providing to eregi()... 3. You didn't escape your \ from PHP, nor eregi(). You need \\\\, I think. 4. You have a space after the $, which is wrong. 5. You didn't escape the $ from PHP with \ Warning: I hate Regex, and have no idea if fixing these will get you any closer to what you want. -- WARNING richard@zend.com address is an endangered species -- Use ceo@l-i-e.com Wanna help me out?
