AppleScript: Help with copying folder to Library/Application Support

Hi,

I'd like to copy a folder named SMFL from a source folder META FILE in a parent folder named My FOLDER to this destination: "/Library/Application Support/SMuFL/Fonts/" but I can't manage with it...

Actually, the META FILE folder include a folder named SMFL where SMFL contains again a .json file named SMFL.JSON, so I want my folder SMFL to be exactly copied here: "/Library/Application Support/SMuFL/Fonts/"

Below is my code:

tell application "Finder"
	
	activate
	
	set SRCMETA to folder "MY FOLDER:META FILE" of desktop
	
	set thePath to "/Library:Application Support:SMuFL:Fonts"
	
	duplicate every file of SRCMETA to thePath with replacing
	
	
end tel

Thanks a lot for your help, and sorry if I'm making any confusion.
