How to count the duplicated lines in VFP ?

Hi Experts !

Could you explain a way to count duplicated lines at a VFP table. I'm using the code below but it doesn't work.
 

select sb_disp, count(sb_disp) as count;
	from DISP_PUB;
	WHERE count(sb_disp) >1;
	group by sb_disp;
	order by sb_disp desc;
	into cursor t_disp

Select allOpen in new window

(Error: File 'count.prg' does not exist

Thanks in advance !
