Cannot embed form as an I frame and embed link looks great on my site, but will not submit.

Hello, I have had a problem embedding my form link in wordpress site. I am not a techie and simply cannot figure what I am doing wrong. In my weebly site, the forms embed and submit with a simple link copy, but in wordpress, they will not submit. They look good and the whole page is functional until we get to the part where we submit and then it says "please wait." I have tried putting it in iframe, but it shows all the gibberish and looks terrible. I want the entire form to be on my page and available to enter the registration info, but it will not work on this site unless I paste the url into  a link and then it just opens as a link. That is not my preference. Can you tell me what I need to do to fix this? 

You can try adding the form WordPress code to your site as a new post/page. This method works for both WordPress.com and WordPress.org site, all you need is copy the appropriate code and paste it in WordPress post/page editor.
