Change parameter value of specific instances

Hi all, As a Dynamo newbie I was trying to understand how to filter lists so I can make changes just to the instances I want. I want to modify the Name parameter of the existing Rooms that contains BEDROOM as part of their Name, but when I attach the filtered List to the Set Parameter node, it won´t do it.

Any ideas what I´m missing?

Hi Pablo,

Make below changes then you will be good to go. You were connecting parameter values to “List.FilterBoolMask”. You need to connect element list.

Brilliant!

Thanks @KULKUL, now it makes perfect sense.
