Lunchbox Create Room by Name and Number - add parameter to node

Hello, I was hoping to (very simply) add to this useful node and associate it with a parameter I have to my rooms by adding “Programming” but I had no luck. Would I have to use a python node for this?

Thank you for the help!

You probably need to review the Transaction.End and .Start nodes. Usually this is because you can’t add or modify the parameters before it has been “Committed” to the model. Can you share with us the code or modifications you made? My guess is you should use other nodes and not change this one.
