Form directs user to wrong thankyou page
 

I am trying to make my form direct the user to the correct THANKS.HTM page
when the submit the form. They keep going to the wrong THANKS.HTM page.

Here's where I want the form to send them...
http://www.astutechoices.com/karakariki/thanks.htm

But they go to another on my pages. Can you spot my error?
I'd appreciate any help.

Hank.
