My link on Thank You page is not working

I have link on my thank you page. But it's not working, keeps going to joltform error page. 

The link in your Thank You page is working properly. I cloned your form and tested it. After clicking the link, it redirected me to your web page. Here's a screen capture:

Is this form embedded on a web page? If yes, please try to re-embed it using the iFrame method. Here's a guide: Getting-the-form-iFrame-code.

If you're still having issues, let us know. Also, please provide more details about the issue. If possible, please provide a screenshot of the error message you're getting.

Hope that helps. Thank you.

Perfect thank u.
