Adding a list to a parameter

I’d like to add a list to a parameter - it looks like it works…
but in Revit all I get is the first 0.

Is it possible to add a list to this?

What exactly are you trying to do here? Do you mean assign a list as the parameter value? That’s not possible as a list describes a structure and parameters only take single values. You could convert the list into a single comma separated value, but that’s about it.

Yeah, that’s my backup :smiley:
Just wanted a sanity check first.
Thanks.
