PHP return value not displaying in field

Hello, I have the following bit of php code:

$res_amount =& $form->data['res_amount'];
$time_res =& $form->data['time_amount'];
$total_price = 0;


$total_price = $res_amount + $time_res;

return $total_price;

When I debug, the return and var are both set to the correct amount, like 12.98, but the field its supposed to go to appears empty still.

I have a 'total' field reloaded on a "price" event upon choosing a reservation time. The total field has value of {var:php15} which happens to be php code.

Any ideas?

Hi Roaf,

The PHP action should be ABOVE the "Display section" action, is it ?

Best regards
