How to pass data from a FileMaker field to an Applescript

I need to delete a file off of my Cincinnati Laser from FileMaker. It gets
it there via a FMScript that export field contents of a container to this
location. So I know the file name and the path its all built in a
calculation field on that record. But I don't know how to get that info
into an Applescript using the FM12 "Perform AppleScript" script step When
I hard code the path and file name (Shown Below) it works.
"set set xpath to "Titanium
Brain:Users:smartin:Desktop:Laser:1512-clr-c.cnc"¶ tell application
\"Finder\"¶ delete file xpath¶ end tell"
When I try to pass the field contents (Shown Below) it doesn't work.
"set xpath to Laser::gCNCPath¶ tell application \"Finder\"¶ delete file
xpath¶ end tell"
What am I missing?
