Variable is undefined: 'NUMBERS_ONLY'

[dimis283]

I have a ready poll related script that use this code obviously to take only number from the form.

NUMBERS_ONLY(request.form("pollselection"))

but there is the error

Microsoft VBScript runtime error '800a01f4'
Variable is undefined: 'NUMBERS_ONLY'

I suppose there is no NUMBERS_ONLY function in asp?
How I can take only numbers from the request.form?

I solve it.
This function is in another file.
