Pass ColdFusion variable through HTML hidden input

I'm making a CAPTCHA for some ColdFusion forms and I can't understand why this isn't working.

<cfimage action="captcha" width="300" height="75" text="#captcha#">         
<input type="hidden" name="captchaHash" value="#captchaHash#">

The above is the code I'm using to create the CAPTCHA within the cfform.

<cfset captcha = makeRandomString()>
<cfset captchaHash = hash(captcha)>

Those are the variables that I set when my form loads. I can put the function, makeRandomString on here but it shouldn't have any bearing on my problem.

Basically, for whatever reason when I process the form the hashed captcha value in the hidden input is not carrying over. I've output it to the screen on the process page and it just says #captchaHash# rather than the hashed value of the captcha. If I output it to the screen on the form page itself before it is processed it works fine. So, I was hoping that somebody could help me pass my captchaHash value from my cfset to my hidden input and solve this stupid problem.

Thanks!

From what you posted it sounds like you just need to wrap the variable in a cfoutput tag to get it to work.
