I would like to get some elements through the GDL parameters, and then through the schedule to get to the GDL parameters. But it does not seem to work right now.
I have tried many methods have failed, please help me thank you!
For me it works with your script: but I cannot see the Parameter "SLAB_MAT_TOP" in your screenshot (in the objects parameters).
If this is not the problem, please post your AC Version und maybe the schedule.xml
