Using variable extractor, 7 variable are created and ID_1, ID_2, ID_3, ID_4, ID_5, ID_MatchNr, ID_rand.
On next requests I implemented loop with Execute Loop ID_MatchNr times and replaced the value with ${ID_n}. In all the iterations, ID_1, ID_2, ID_3, ID_4, ID_5 were not called or fetched. On looking at the request I found ID_n in the request.
Please find the screenshots in attachment.
