Hi @Zacz , welcome to the community!

Use Excel import and use set parameter Node. Might help with your task.

Try from this template

Mark value from Excel.dyn (23.2 KB)

oh ok thanks i try to use that

I’m sorry I didn’t fix the data flow part, can you explain it more or can you show me how to do it?

how do I know-how is your data!

Sorry, I don’t know what dataflow is, I haven’t heard of it before.

This would be you getting the data from your families and/or excel and comparing them. We can’t see the families you’re working with or their parameter/type names so we can’t design that part of the script for you.

This is a common issue on the forums where we can only give guidance when it comes to the context specific portions of a script.
