OK, that was one of those "other ways" I initially mentioned but I was trying to stay with your original request. Either way I'm glad you got it working.

However, if you find some extra time could you first verify my last reply actually does what you wanted and also compare the time your version and mine take? Or if it's easier to send files with 13K results and 500 removers I'd be glad to do the comparison myself.

Not like it's that important since you've answered your question. I'm just curious about which is more efficient in regard to speed and resources. I'm guessing creating the $FinalResult array is quicker.
