You've created a file (or a page) and from that page, you would like to have a link to a form, so here's how you go about that.
NOTE: If you would like to have more control over the display of the form, make sure you have a created page for that form to land on. This tutorial will take you strictly to the form itself.
1) In the form manager, select a form. Under the widget ID, select "Click here to test a live version of this form"
2) Go to the page, highlight and copy the entire URL
3) Now, go to the form or page you created and create the hyperlink!
Now... tell your co-worker, "I just totally crushed that form...". They probably won't get it, but that's ok.
