Not being a regex expert I was hoping someone could point me at a
list, forum or just give me a pointer on how to achieve this:

Field that must have 2 out of 3 of these:

standard a-z/A-Z
arabic numbers 0-9
special chars %$#@

[EMAIL PROTECTED]|[A-Za-z0-9]+|[EMAIL PROTECTED]


Maybe something like

[EMAIL PROTECTED](?(?<=[A-Za-z])[EMAIL PROTECTED]|[EMAIL PROTECTED])$


Actually on second thought you may want to drop the first ?. It also depends on whether the characters specified in the above 3 conditions are the only allowable characters or not.
