Hi Morten,
The advice I got from the group on using variables in the Expression Editor was excellent, but like you I struggled to get the Expression Editor instead of the Selector Editor. As you found out, variables don’t work in the Selector Editor. Instead of using record or data scraping to define the object you want to manipulate with the Expression Editor you have to manually drag the object from the list on the left. Then when you go into its properties the Selector will bring up the Expression Editor instead of the Selector Editor. What I now do is use “record” to stage my process, then delete the object on which I want to use the Expression Editor and then manually added it back. And like magic, I am the able to manipulate it with the Expression Editor when I click on the Selector.
I hope this helps. If not let me know and I’ll try to re-explain what I do to get the Expression Editor.
