I need some help to query a result to print out in a .txt file. The result is, by matching two tables in File1.txt and File2.txt.

For example, matching Rev ID from File1.txt with File2.txt, say PROD_2_1, the result should print to an output file all the Rev IDs after and including that Rev, such as PROD_2_1, PROD_2_2, its corresponding PROD ID and the Date Released.

This is File1.txt, File2.txt, and my code, which does not print all the Rev IDs after that version. Can you please help me where my code is failing?
