External form not working

I’m using Webflow for design and prototyping and have done so for years. I use the code on an external CMS and that includes an external form system. Normally this is no problem. I know not to include “w-form” on the form tag.

However, on my recent exports, I’m having a problem getting the external form to submit. It appears to be a javascript problem because disabling the main Webflow javascript file allows the form to work. The submit button itself does nothing when clicked.

My question is - what portion of the Webflow javascript can I remove so that my external forms work? Or is there a way to export the code so that no form code is included?
