What i am doing wrong ?????

You misplaced the () . You try to pass two parms to the tonumber function and that is probably not what you want.

tonumber (e [, base])
Tries to convert its argument to a number. If the argument is already a number or a string convertible to a number, then tonumber returns this number; otherwise, it returns nil.
An optional argument specifies the base to interpret the numeral. The base may be any integer between 2 and 36, inclusive. In bases above 10, the letter 'A' (in either upper or lower case) represents 10, 'B' represents 11, and so forth, with 'Z' representing 35. In base 10 (the default), the number can have a decimal part, as well as an optional exponent part (see §2.1). In other bases, only unsigned integers are accepted.

Code: Select all

local kwhKosten = tonumber(dz.utils.round( (kwhPrijs * vandaagKwh) + kwhPrijsVast, 2 ))

or even better (because the result of dz.utils.round is always a number)

Code: Select all

local kwhKosten = dz.utils.round( kwhPrijs * vandaagKwh + kwhPrijsVast, 2)

All values are there but no result.
