The view works, but not when embedded on a page? Sounds odd. Can you describe in some detail what you have an what you are trying to do? For starters, what does the redirect look like?

The view isn't working properly as I don't know how to set the id to be the form just submitted.
I've created a form and for the output I have a Quiz outcome. I've put conditional information in there, based on scores calculated on the form, and I can display it once the form is submitted. 
However, ideally I want to take the user to a new page with the outcome on, so that I can also append some additional information such as how to make an appointment and add a video etc to that new page.
I'd thought maybe I could use the general settings so that ON SUBMIT instead of displaying a message and the quiz outcome I could redirect to another page that contained the quiz outcome.
I thought maybe I needed to create a view to put on that page, but now I'm not sure as my view seems to have a fixed id in, not the entry that's just been made.
I can't find any videos or instructions on how to put that quiz outcome somewhere else.

Your best bet is to read this: https://formidableforms.com/knowledgebase/create-a-view/#kb-display-a-single-entry

You can change the filter for entry ID to something dynamic like [get param=entry default=none] if you're including the entry ID in your redirect link. Your redirect should look something like https://myurl.com/?entry=[id]

Thank you :)
