Update Thank You Page Condition Not Working

I have this form:
https://www.jotform.com/build/250574975451162

I have a hidden field popup with a condition set that if popup is "true" redirect to a different page. I'm passing this as a query parameter and can confirm that the field is set to "true" but the form continues to redirect to the default redirect url.

Hi Peter,

Thanks for reaching out to Jotform Support. I cloned your form and tested it to see if I could replicate the issue, and I ran into the same issue. When I looked at your form, I saw that the Change Thank You Page condition wasn't configured correctly. Let me show you how to fix it:

1. In Form Builder, click on Settings in the orange navigation bar at the top.

2. Choose Conditions in the menu on the left, then hover your mouse over Condition #1 and click on the Pencil icon.

3. Set the condition as you see below, then click on Save.

You'll notice I replaced true with TRUE as that's where the issue is coming from. And to keep the conversation organized, I moved your other question to its own thread, and someone from our Support Team will help you with it here.

Give it a try and let us know if you need any more help.
