Opening various files with Applescript and copy to field

I receive several mails and each mail has an attachment generally with people CV.

My database imports the email messagtes and tells me the patf for the various CV files.

They come as PDF, DOC, DOCX or other formats.

Through the Mac I am always able to copy the text no matter what the original file is

How can I create a Script which using Applescript does something like

tell application Finder

to open the file

pause indefinitively

paste or go to next record?

Each Record has a text field called Attachements with the file location such as

MYMAC/Users/DANWAN/Desktop/Job-Mails/Danwan/INBOX/CV_Nam_2012-507de0081d207.pdf

or

MYMAC/Users/DANWAN/Desktop/Job-Mails/Danwan/INBOX/CV_Name_2012-507de0081d207.rtf

or

MYMAC/Users/DANWAN/Desktop/Job-Mails/Danwan/INBOX/CV_Nam_2012-507de0081d207.doc

However this script gives me always an error: Object Not found with an Applescript unknown error -1728

this is the Applescript

tell application "FileMaker Pro Advanced"

tell database "Jobs"

tell table 1

set Ifile to field "Attachments" -- getpath

end tell

end tell

end tell

tell application "Finder"

open Ifile

keystroke S -- select the whole file

Keystroke C-- copies the file

Keystorke W -- closes the fil

end tell

I always get "Object not found"

How can I get this task so I can set the clipboard to the selection and if I need to. past it to the field

Curriculum?

Thanks a lot
