I have the following code sequence:

select tblRawData
	
set filter to PermID == lcPermID and ((LoDrive + HiDrive)/2 + (LoCpool + HiCpool)/2 + ;
	(LoBike + HiBike)/2 + (LoBus + HiBus)/2 + (LoWalk + HiWalk)/2 + ;
	(LoAtHome + HiAtHome)/2 + (LoField + HiField)/2 + (LoOther + HiOther)/2) > 7

go top
if ! eof()
	messagebox("The following records need to be checked for Mode Use over 7.")
	set fields to permid,Sequence, Company, LinkField, ;
	LoDrive, HiDrive, ;
	LoCpool, HiCpool, ;
	LoBike, HiBike, ;
	LoBus, HiBus, ;
	LoWalk, HiWalk, ;
	LoAtHome, HiAtHome, ;
	LoField, HiField, ;
	LoOther, HiOther, ;
	InDrive, LoDrive, HiDrive, ;
	InBike, LoBike, HiBike, ;
	InWalk, LoWalk, HiWalk, ;
	SpOther, InOther, LoOther, HiOther, ;
	InCpool, LoCpool, HiCpool, ;
	InBus, LoBus, HiBus, ;
	InAtHome, LoAtHome, HiAtHome, ;
	InField, LoField, HiField 
	browse
	set fields to all
endif

This produces an error on the browse to the effect that "variable permid is not found".
Any ideas as to what is causing this? The sequence works fine if I delete the set fields statement. permid is a character field and does exist in the table.
