What would I need to do to post the data on the form?

SO if I wanted to do a straight HTML page, what would I need to do to post the data on the form?

The question is a bit confusing and not clear enough. May I request to provide more clarity.

Were you perhaps wanting instead to pre-populate the embedded form on the website?

You can do this via the URL parameter pre-population methoed.

OR

You can also use the Prepopulate App.

I hope this help. Please reiterate the question so that we can provide you with the more appropriate suggestions also.

Thanks.
