    Resolved [RESOLVED] Regular Expression Help Needed

    Hey guys,

    I am in a need of a Regular Expression to restrict input to only certain characters in a text box. Any help would be gretly appreciated.

    The text box can only allow 0 or 1 "+" sign at the beginning and at no other position.
    The text box can only allow 0 or 1 ":" sign not before the "+" sign.
    The text box can allow any number of 0-9 digits.

    e.g.

    10 = GOOD
    +10 = GOOD
    +:10 = GOOD
    :10 = GOOD
    12:20 = GOOD
    +12:20 = GOOD

    No other characters allowed.

    Hope this makes sense.

    TA
