Nowhere do you output the filenames. Are you sure that the filenames as stored in $rrconfig::locotemp, $rrconfig::availlocotemp and $rrconfig::availynglocotemp are what you expect them to be?

Also, check the original filenames as well, and output these as well.

If the third file always remains unchanged, my guess is that you're not even generating it. Move the third file away and likely your program will still work.
