the script works good, thanks for it. I am facing now a minor problem with "duplicate variable names", due to the following reason:
Before renaming: "Temp_01_free", "Temp_02_free", etc.
After renaming: "Temp_free" in all cases. Is it possible to number the variables then as long as they are repeated? For instance: "Temp_free1", "Temp_free2", etc.
