Thanks Natalie and Miles! The loop thing worked. What I had tried before was
put the echo inside the loop and it wasn't working, but now it does, w00t!
Thanks!

Dave,
You're v. close to an answer. Think about it a bit.
Initialize a variable before your loop, setting it to zero.
$tot = 0;
In the loop, add the amount to that variable,
$tot += $num_to_add;
OR
$tot = $tot + $num_to_add;
After the loop, echo $tot.
