This is not proper CFML syntax:

<cfif id="userInput" eq Hash(#form.userInput#)>

What are you trying to do exactly in this line? I think you meant:

<cfif hash(form.userinput) eq form.hashval>

We want to compare the hidden form field, form.hashval, which was a
hash of the captcha, with a hash of what the user entered.
