An array as a parameter when calling a function does not need the bracers. Take out the "[]" and it should fix your problem.

Post your errors, too.

function does not take 3 arguments

But now it's giving me these errors? How can i pass 3 parameters in an argument?

[r64]

Make the function float, and don't pass three arguments to it. I can't bother read all your code, but you can't enter a float number into an integer.
Also, currentSales seems to be undeclared.

ok, did. This is the code i wrote now,
