I added a couple of parameters on a step template and it turns out I don’t need one of them… but, to my surprise, there is no way to delete a parameter.
In the top right corner of the parameter (on the list of parameters tab), there’s a little cross - clicking that will delete the parameter (after you click Save). Let me know if that doesn’t work for you!
Paul - Thanks. That worked. They were just very subtle and I missed them.
