i am trying to mutiply and add 2 dnamic texts on a php form, but i do not seem to get the reply, but i get the following results

"sum (4 + 1)"

This is the code that i typed in

(<?php echo $row_standings['w']; ?>+<?php echo $row_standings['d']; ?>

The 4 is the result of `w` and 1 is the result of `d`

I would like the that two figures add up on the screen, i also need to multiply other dynamice texts.
