What's wrong with this code?

CREATE CURSOR tickets(ticket i(4))
SELECT tickets
FOR m.i=1 TO 500
	APPEND BLANK
	replace ticket WITH m.i
ENDFOR
SELECT tickets
GO top
LABEL FORM ticketlbl PREVIEW 

The label has an image on it, and one field, Ticket. When the line, label form ticketlbl preview, executes, it errors with variable ticket not found???

The table tickets in a browse, has 500 records with a field ticket which has values from 1 to 500.

TIA,
Mike
