Is there a way to use conditional text boxes to link to an external page via a Thank you Page?

I have my form set up to have the user enter the conditional text but it directs to the external link via the thank you page whether they enter the correct text or not. I don't see an option to have it so it only redirects with a correct response. This is probably because I'm not very computer savvy! Any help would be appreciated.

I have checked your form and did not find a condition to change the thank you link based on the text box input, you need to set it up so it redirects to the desired link if the input is correct.
