Help with a regular expression

    Hi
    Please help

    This is my regular expression:
    \$(\d*?)(\.*?)(\d*?)

    (a dollar, followed by 0 or more digits, followed by ., followed by 0 or more digits).

    I just need to check that the string is no longer than say 8 characters long, including the numbers, . and dollar sign.

    I know how to restrict the length of any string to 8 letters
    ^.{1,8}$
    but I'm having trouble combing this with the first expression


    Help!:D

    ^\$[0-9]{0,2}$

    Start from that

    This seems to be working :

    ^[\$(\d*?)(\.*?)(\d*?)]{1,8}$

    The square brackets make the difference, I'll have to look this up:confused:

    The square brackets are groupings, you should probably have one for each side of the decimal.
