passing the multiple parameters using the replace function in ssrs

below is my query

this query is wokring fine in work bench but when i copy this query in to data set and preview the report its throwing the error as replace function needs 3 arguments.

i even tried by replacing exe to select to check out whether the multiple values are passing correctly r not in work bench,its working fine but not able to make out why its throwing error in ssrs.
