applescript issue

i have an applescript done by another vworker. i was dumb enough to pay him before I tested. he did it and it i works kind of but at this point is unuseable. i don't have a mac and only am able to test two times per week. the script is very simple. uploads a large mp3 file to an ftp site when you drag and drop the file to it. then it loads a php script via a url on safari and then shuts down the compture... or atleast it is supposed to do that. currently it will upload a small file but not a large file. it turns off the computer while you are uploading a large file. or just never completes the upload. this is a church project so I can only test wednesdays and sundays when i go to church. i am hoping this can be modified to use a command line program like filezilla so that there is some visual indicator of what is happening with the upload and if it is working.
