Select walls in phase and change instance parameter

Hi Everyone,

I’m still a newbee on Dynamo and can’t find what’s wrong with the end of my script.
I want to filter walls by their creation phases then when I get the good selection, I need to modify an instance text parameter (“Test” in my exemple).

It looks like the wall selection works but once I try to link that selection to “Set parameter by name”, it tells me the instance text parameter doesn’t exist. I can’t see what I’m doing wrong here.

Thanks in advance for your help!!


You need to filter the walls by phase. Right now you’re filtering the phases and trying to set the Test parameter for phase instead of wall.

Well, I think now should be better, but still have some issues with walls…
When I choose a floor/ceiling category, it works fine. What I don’t get is why does it fails when choosing Wall category??? Phases are the same whatever the category, my project parameter is set for the 3 categories…

Would somebody know what I’m doing wrong still?

… Made it from scratch again and it finally works! Don’t get why it didn’t at first…
