Instead of passing the name/id/number of the field, why don't you just
pass the contents of the field to the XFCN?  I.e.:

	on mouseUp
		put card field "some name or id reference goes here" into parameter
		myXFCN parameter
		put the result into card field "some name or id reference goes here"
	end mouseUp

This will keep your XFCN simple.  I don't see why you'd want to make it
more complicated than this, what flexibility are you gaining?
