Thank you Jason. I'm not sure why we were having the validation problem. The other person involved was getting the same trouble on his computer while at home and traveling. I was having the trouble on both of my computers. We would answer the captcha and the security question definitely correctly. But, on a semi regular (but random and not all the time) basis it would not be accepted. I just tried twice and it validated correctly both times. Not sure what to say but thanks for testing it.
I was successful in removing the security question. On my previous tries I was leaving out the last step "delete line 18". I guess i needed to scroll down to see it or something. I have removed it now and tested the form and it validates correctly and returns the thank you page. I feel kind of stupid......
Thanks for all of your help!!
