Overflow on mobile... Wheres it coming from?

Hey everybody, I’m having an issue that only occurs in the vertical layout on mobile. For some reason I can only view the published creative-brief page when I don’t hide the overflow that I would like to. When I do hide the overflow on w-custom-form, it changes the entire page to the background gradient being the ONLY visible element… The desktop version works fine.

This is first post on here - if more information is needed to asses the issue I’ll do my best to explain further. Sorry if this question is dumb - it seems like such a simple issue - but I’ve been struggling with getting it to work all day and have finally resorted to asking for help.

Thanks in advance! -Robby
