**What are you trying to accomplish**  
I am trying to put a custom Javascript code from Formstack using the custom code content block. The form doesn’t show on either side. I have tried to separate the script tags. I tried the Advanced Options and still am not able to see the form. The code works with iFrame, but I need it to be embedded by JavaScript for tracking and iFrame does not allow tracking.

**Code stack you are integrating Builder with**  
Next.JS, React, i think. I dont have access to the entire code at the moment

**Reproducible code example**
