You're missing a semicolon proceeding your function declaration. Try adding that on, and report any other errors that you might have. The error reports would be extremely helpful to us. - Rolos

is loan_amount in the right scope? wouldn't it have to be a global variable for that or does it work fine as an equals. should work if a value is returned

loan_amount is in the scope of main and is not passed to this function, where it is used: double amount(double p, double r, int m) Therefore, you need to either have it as a global variable or pass it into the 'amount' function where it is used. IR

Yeah! That's right! Declare your function before main(). Sorry about that. - Rolos
