I am trying to update Wall type parameter "Assembly Code" but getting error

in “Set Type Parameter” node you have connect the value of the parameter as a “Element " input
you have connect it from the " All Element Of Category” node

Thanks Khuzaimah but again i am getting new error

i dont get it why do you divide the value of parameter with string values. this with get you null value
what are you trying to get , i may help you

i just want to update type parameter of wall named “Assembly Code”

if you want to use value of “ABCD…” as a assebly code, connect it directly to set parameter node

Hi, where I can get the node “Get Type Parameter”, I try to get parameter “assembly code” as well. May i ask you please what kind of packages are you using in this script?
