<snip> I run this mysql query: "select sum(quantity)*price,price from sale where dvd_id=1 group by price"; I get this result: sum(quantity)*price price 450.00 15.00 29.99 29.99 I want to display the sum of the values in the first column (450.00+29.99), but I cannot figure out how to do this! Can someone clue me in? </snip> <?php // Multiplying with varaibles $factorA = number_format(system_value('sum'); $factorB = number_format(system_value('price'), 0); $product = $factorA + $factorB; echo $product; ?> Something like that? You'll have to obviously play with this to make it work for you. But calculations work like your Windows Calculator number keypad. + = plus - = minus * = multiply etc...
