Hi Simon,

Thank you for your reply, yeah I have the Query XML as part of my workflow to get the XML value from the repeating section and stored that value in a variable collection. The result of my variable collection is with the semicolon as the delimiter. I want that delimiter remove and split the value to get the result I want but for some reason it does not work.
