Having a difficult to set up a pop up

We're trying to make a popup on a specific URL. The popup includes some text, and html form tags, and javascript(Code from Infusionsoft)

• When I include the HTML Form tags and Javascript, I can't even see the preview. It doesn't show up at all.

• I tried to test a popup on a specific page, I set status Active, and typed in barefootinvestor.com/home/jobs for a test, at 'On specific URL'. (didn't include any tag or script) But it didn't work.

We're on the latest version of Wordpress and using W3 Total Cache plugin.

Please let me know what should I do to use the popup plugin properly.
