Hi, It seems no matter how hard I try I can't get these things to do what I want. This one should be easy... It just won't work for me. I need to make sure a string contains a-z or A-Z it may also include 0-9. If someone would please give me an examplle of such a statement I would be most greatful. Also, if you happen to know of a tutorial that explains these type things let me know. Functions like preg_match are very useful, but only if you can get them to do what you want. Thanks BlueScale
