[RESOLVED] Form mail + Recaptcha script

I am using a ASP script to parse an HTML contact-us page and send an email. I also implemented recaptcha into the ASP script and it's working, but I run into an issue when I attempt to response.Redirect the user to the "contact_success.html" page.

If I comment out the response.redirect line and use response.write it writes a blank message "thanks for your comment" fine, but I really want the regular look of my website experienced by going to "contact_success.html"

So my issue is I can't redirect to a confirmation page.


Below is the error I receive after successfully answering recaptcha and failing to redirect:

Microsoft VBScript runtime error '800a01a8'

Object required: ''

/contact_us/contact_us.asp, line 125


Below is my code (the error is pointing to the line "response.redirect(contact_suc...)":

Code:

The script has no problems with Response.Write but I run into issues redirecting. Some variable needs to probably be set to NOTHING.

I'm not sure which variable is not resetting to nothing, but the script used to write my recaptcha response (whatever the user typed into the recaptcha field) to the page.

I fixed that issue somehow.
