Once you have an Action Set set up to get a list the next step is to use it in a page.
1. If you haven’t done so already, add an Opt-in Form or Popup Opt-in to your page, if you’re modifying an existing form hover over it and select ‘edit’
2. In the ‘Edit Opt-in Form‘ panel on the left select the Form tab.
3. From the ‘Associated ActionSet‘ drop-down list chose the Action-Set that links with the List or Webform you wish to use for this page.
