I have been working with this for awhile now and cannot seem to get it right. I have a main page (contact us form) where the user fills in their information, once done they are redirected to another page thanking them. I have been trying to add a cookie on the main page that tells if the user has already filled out the form and send them to a whole new page stating they have already filled the form out. Here is what I have.

Contact us page
