you multiply by persantage/100.

if you add persantage then first you find what the persantage is (though multiplying) then you add.

 code: total := subtotal + subtotal*15/100

or you can just use 0.15 which is same as 15/100

Do you know a little of the code just an example so i can see how it is done just wondering i think i know what you mean.

 code: var choice:boolean:=false %declare the var as false... make it true later on in your %program, if something happens that makes it true %your code here if choice = false then %do whatever else %do whatever if its true end if
