Make it possible to concatenate the values of two variables into the third one

Hi Omar,

I'm not sure, but I think this could be a timing issue. Since you're trying to do it all within the same request, it's possible that LoadComplete is trying to process the variable concatenation before it actually saves those parameters to their respective variables.

I suggest doing the variable concatenation in a data selector for a subsequent request (i.e. requests 5-9), and then try using that concatenated variable where you need it in request 10.
