I can’t make it work 
import rhinoscriptsyntax as rs
def LinkBlock():
Ids = rs.GetObjects("Select blocks to link.", filter=4096, preselect =True)
if Ids is None: return
path = "C:\Users\Shynn\Desktop\BlocksToLink.3dm"
for Id in Ids:
name = rs.BlockInstanceName(Id)
filepath = path + "\\" + name + ".3dm"
rs.Command("_-BlockManager _Properties " + chr(34) + name + chr(34) + " _UpdateType _Linked path _Enter _Enter", False)
if name == “main”:
LinkBlock()
I get this error:
