Getting Infusionsoft form code to look right

Hello,

I have some form code that was provided by Infusionsoft.

When I put the form code on a page, this is what I get:

https://fitranx.com/form-test/

I would like to change it so that it looks more like the form at the bottom of this page:

https://fitranx.com/can-you-pass-level-1/

Could anyone help?
