 me again sorry.

right then. I have set the value of some variables and am trying to add them together but I can't get it to work.

$subtotal = "$Q1+$Q2+$Q3";
echo $subtotal;

all this does is print the values seperately withn the sign. :no:


Any ideas?
Thanks again

 Of course.. Do this:

Code:
 

<?php

$subtotal = $Q1 + $Q2 + $Q3;

echo $subtotal;

?>


(You don't do math around quotes, my friend.)
