Forum - Worked in Perl but not in ASP

Hi,
I have used the captcha code in perl successfully but I have one
server where I have to use ASP not perl, but when I add the code at
the beginning of the script as advised it doesn't matter what code if
any is imputed the form is also sent.
The captcha is therefore not being checked for acuacy.
What am I doing wrong or is there an error in the coding?
This is the asp form script I am using and I have added the captcha
script at the top (hopefully I have highlighted it in bold type)
<%@ LANGUAGE="VBScript"%

Hi Please ignore the <b> and </b> in the captcha script, I was trying
to show them in bold on the forum which obviously didn't work. they
were not used in the asp form.
