Which database are you using? It will make a difference in how to do this.
Generally, you'll want some type of FOR loop:
ATTENTION: THIS IS NOT REAL CODE, JUST AN IDEA
$num_results = count (results);
for ( $i=1 ; $i <= $num_results ; $i++ ) {
fetch_row ( results );
$grand_total = $grand_total + results[$i];
}
