I have this: {{#expr:{{GEP|Plain pizza}}-({{GEP|Cheese}}+{{GEP|Pizza base}}+{{GEP|Tomato}})/143 round 0}} It is supposed to get the price of a plain pizza () minus the prices of Cheese (), Pizza base () and tomato () together, then divide that by 143 and remove all the digits after the decimal point. So can anyone see anything wrong with that code? Cause it returns which is obviously incorrect.

You forgot two parenthesis. {{#expr:({{GEP|Plain pizza}}-({{GEP|Cheese}}+{{GEP|Pizza base}}+{{GEP|Tomato}}))/143 round 0}} 222 talk 11:47, September 9, 2010 (UTC) Are parenthesis these () ? Why would I need 2? User:-Matt/sig 11:49, September 9, 2010
