So do you just want a dropdown list with all the names in the Genre column, so the random choice will be from the particular genre ?

Code:
Name	Type	TSig	EvSw	Tempo	Long Name	Genre	Group	Date*	Set#	#Instr	#substyles	Other Genres	->Debug Order	GenScore	Priority	RDsub	RTsub	Fav	Rec	nr	NA	Pack	8/16	Instruments
