thanks for the reply I understand what u r saying but surely it would process eventualy when the file is complete? as it runs every minute. The file will not process even if i run it manually on the new file that has come in even after waiting a couple of minutes. It's only after i change the script slightly will the file process corectly until a new file appears next day.

I will try what u have suggested as I have run out of ideas. Thanks again.
