27	+
28	+ = How do I create ActiveCampaign subscription forms to use in WordPress? =
29	+
30	+ You need to be using [ActiveCampaign email marketing software](http://www.activecampaign.com/) to use this widget. Create new subscriptions forms in the software by going to the "Integration" section, then they will be available through this widget.
31	+
32	+ = I get a "Connection failed" message. What does this mean? =
33	+
34	+ Please make sure that your login information is correct, and that you have at least one Integration form already created in the ActiveCampaign system.
35	+
36	+ = What does "Fetch form with each page load" mean? =
37	+
38	+ If you check this box, WordPress will re-request the details of your form each time the page is loaded. For performance reasons, it's best to leave this box unchecked.
