This script worked in os9 but not in osx?

[sonrise]

set field {"GBL. Resume URL", ""http://(host computer ISP #)/"&Right(Applicant ID, 1) &"/"&Applicant ID &".pdf"}

open URL {nodialog, "GBL. Resume URL"}

can't figure out why if the files with all our resumes are hosted on a computer with os9 this script works fine but If I move the files to a computer with os X it doesn't work

I've already put it in the public folder, the shared folder and the sites folder, i've enabled almost everything dealing with sharing in the syst prefs

i just can't figure out how to make filemaker pro 6 pull up a specific file from another mac with osx.

any help?
