Code has to calculate the difference between the old and new price I did something like this:
{math equation="(y-x)/100" y=$old_price_brutto x=$price_brutto format="%.2f"} This code does not work
When I put the numbers is no problem calculates the difference
for example:
{math equation="(y-x)/100" y="100" x="20" format="%.2f"}

Thank you for your help !

{math equation="(y-x)/100" y=$old_price_brutto x=$price_brutto format="%.2f"}

is correct code.

Are you sure that you have assigned the right values to $old_price_brutto and $price_brutto?

Add
{$old_price_brutto} {$price_brutto} to check the values
