Hey, I’m struggling to understand where I can find the action parameters mentioned here. Are they supposed to be there automatically, or do I have to add them somehow? I can’t find them in the context parameters inside the action. I tried adding two View action parameters myself, but I can’t find anything called “target view” or “source view” to connect them to. What am I doing wrong? Thanks! ![Skjermbilde 2024-03-19 kl. 12.22.49](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/6/64d8d1679af5bfb68947db8a8a62c1794a827d4e.png) ---

Hello Petter. To use the action params available on `On Browser History Change`, you first need to define atleast one action param in your action. This action param must be of type `string`. Hope this helps 🙂 //Erik ![bilde](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/0/04ca41d5e871c237ba913c23a6ee3df3d68bdebc.png) ![bilde](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/a/ad6b292998da40ef94005fb76a96614a59e94ff7.png)
