identify if numbers only in a string

[Igal]

Hay.
in one part of my application i have some kind of user and password
form.
it asks for e-mail and a costumer id (as password), the costumer id
must be a number, it's an INT in the SQL table. i tried to use a
javascript checking method, but this kind of checking method seems not
to work at all in firefox, so i'll do the checking via asp.

what i need to know is how to check if a some VAR got anything except
numbers in it?

<script language='javascript' runat='server'>
function notAllDigits(x){
return /\D/.test(x);
};
</script>

<%
response.write notAllDigits("12345X")
%>
