Oops, sorry guys...girlfriends on holiday so have not had my "medicine"
:-)
and am also braindead right now...
basically...how do I get the average?
$pic_no_of_votes --- > holds the total number of votes (eg: 212)
$vote_total_pts ----> holds the total points from all those votes (eg:
1027)
how do i get the average down to something like: 3.23 or 1.02 or 4.11 etc
Thanks,
Ryan
