When you have buttons in an interaction, you always want to define what happens when a button is clicked. For this you need actions.
On the Design page in Interaction Builder, click on a button element and choose "Actions" from the panel on the right and click "+ Action". This will open up a drop down menu from where you can choose your desired action(s). The ones most frequently used are:
- Change view: choose which view will be displayed for the visitor. Views can be found at the bottom in the "1. Design" view.
- Exit: Close the entire interaction
- URL: Direct your visitor to a website (through redirect or through a new tab)
You can add several actions by clicking "+Action" after your initial action. These actions will be triggered in order from top to bottom.
Have a look at this guide if you need tips on how to use these actions.
