HI @vishalghuge2500 ,

You’re applying the Transaction.End node in the wrong place, you should use it after the FamilyType.Duplicate nodes. Then using a PassThrough node make sure those nodes are executed first before writing the parameter-values. See the example below for reference if you find it hard to follow:
