CF Mail Form Validation

[Newsgroup_User]

I am putting together a form where one of the fields needs to be an 8
digit number that begins with a 0(zero) and ends with a 0(zero).

I know this is possible to validate with the onvalidate code, but what
is the correspoding javascript needed to make sure that the number is
exactly 8 digits and the first and last digit are 0(zero). If these
parameters are not met, it will not let the form be sent.

Any thougts as to how to code this?

There is another post just like this in the General Discussion forum. It has answers in it. Might be worth a look.
