C# challenge

Looks like I'm still getting an error on this one. Honestly wish it would let me skip it or show me the answer after 2 d

Program.cs 
using System;

class Program
{
    static double Multiply(double firstParam, double secondParam)
    {
        return firstParam * secondParam;
    }
    static void Main(string[] args)
    {
        Console.WriteLine(Multiply(2.5,2));
        Console.WriteLine(Multiply(6,7));
    }

}

For the Method Parameters code challenge that you linked to in this question, the function Multiply shouldn't return anything.

For the Return Values code challenge that you previously linked to, you need to print out the sum of the function calls.

I'm confused. So I should leave off "return"?

using System;

class Program
{
    static void Multiply(double firstParam, double secondParam)
    {
        Console.WriteLine( firstParam * secondParam);
    }
    static void Main(string[] args)
    {
        Multiply(2.5,2);
        Multiply(6,7);
    }

}

Since the challenge is not expecting you to return anything from the Multiply function, the function's return type should be void instead of double and Console.WriteLine needs to be within the function.

I'll try that. Thanks!
