Hi,

What, specificly don't work?

Do you have a file called 'test_predictions_1', that have ids in the range 1 to 1000?

Are the print "file: $file\n"; and print "id: $id\n"; printing what you expect?

Why do you have a second close (LOOKUP); outside the foreach loop?

Can you provide us some specific data that you think should work and is not working?
