perform find on remote filemaker database

I would like to perform a find on a Filemaker database that I have opened remotely. Every time I run the code below it woks perfectly if I open the database on my local machine but if I open it remotely the script errors with

and it highlights

part of my code. I have other parts of my script that are inputing and retrieving data from cells in the remote database without any problems, it’s just having problems with the find request.
Any Ideas?

tell application "FileMaker Pro"
	tell database "PreFlight_Tracking.fp7"
		delete every request
		set therequest to create new request
		tell therequest
			set cell "Stage_1_Preflight_Success" to "000083_01_29590818-190981_AM.pdf"
		end tell
	end tell
end tell

I haven’t used the “request” command in FileMaker. I have accessed a FMP database using the following method though if you want to try this approach:

set searchValue to "My Name"
tell application "FileMaker Pro"
	tell database "Database_1.fp7"
			tell (first record whose cell "main_cell" = searchValue)
				set data1 to get data of cell "data1"
				set data2 to get data of cell "data2"
			end tell
		on error
			display dialog "Error getting values."
		end try
	end tell
end tell
