Don’t assign value to in_TransactionNumber as 1 here. The value will come from TransactionNumber variable in Init state.

And also before if condition print this value using message box and see whether it is display any row count or Null value exception.

Out_WIList.count

That means either it did not scrapped data or may be you did not pass arguments properly.
