Newbie here, show (every record ...) not working now

[newbie_sam]

I have a applescript that use to work but is no longer working, very simple.

property DB : "CBA Jobs.fp7"

property aPO : "046860"

tell application "FileMaker Pro Advanced.app"

activate

try

show (every record of DB whose cell "Media_Bank_PO_Number" is aPO)

on error

show (every record of DB whose cell "Media_Bank_PO_Number" = aPO & " - Datatrak")

end try

end tell

The po exists on the database. I can do a manual search. But when I trace the code it jumps to on error.

Any help will be greatly appreciated.

DB is remote
