Script Method Problem

[armbar]

I have over one hundred mp3 files, of which I need to remove the first 10 seconds. With batch processing I used the script method but I have a problem. When I press record on the script window I select the first 10 seconds and delete it. When I press stop and begin batch processing all the files using that script adobe audition does not delete 10 seconds, it deletes the selected area in terms of scale not time. (Hope that makes sense) basically all the files are different length and size and this script ends up deleting different portions of each file not just 10 seconds. How do I delete ONLY the first 10 seconds using the script method? Thanks.
