My form does not show up in my SquareSpace webpage.

I am designing a website that needs "Upload" options (which your forms allow) and I have tried ALL of your embed options from the code to the frame. On squarespace I have tried putting into into a code block or just straight up embedded it, however, a message appears in the block the form is supposed to pop up in saying "Embedded Code: This block contains embedded code and will only be rendered on the front of your site". I am quite confused. Maybe you can clear that up for me

Also, how do I connect my e-mail to the form so that whenever somone submits it is directed to me?
