when the total of what is supposed to be added shows the total. It shows it with 3 decimal places, how do i get it to only be 2?

You can round numbers in PHP to two decimal places by using:

PHP Code:

$num = round($num, 2); 


If you want to just truncate to two decimal places, you can do:

PHP Code:

$num = round($num-0.005, 2); 


PHP Code:

$num = number_format($number, 2, '.', ',');
