Attempting the Challenge on Return Values

Question

I'm attempting the Challenge on Return Values and the console keeps saying I'm missing semicolons, 
Am I?
```Program.cs
using System;
class Program
{
static double Multiply(double firstParam, double secondParam)
{
    return (firstParam * secondParam);
}

static void Main(string[] args)
{
   var double Num1;
   var double Num2;

Num1  = Multiply(2.5, 2);
   Num2  = Multiply(6, 7);
   Console.WriteLine(Num1 * Num2);
}
}
```

Hi there, @Donni Honig (https://teamtreehouse.com/donnihonig)! Yes, and no. However, this would be the same error you would get if you attempted this in Visual Studio or any other compiler. The var keyword is used when you don't want to specify a type and you want C# to figure out the type itself. The double is explicitly setting the type to double. You can't have both at the same time. It must either set the data type implicitly or explicitly.
Any variable that uses var must receive an initial value at the time it is first declared. So where you have:
```cs
var double Num1;
var double Num2;
```
It's wanting:
```cs
double Num1;
double Num2;
```
Also note that the challenge is asking you to add the results of these two together, not multiply them. So in your final line where you have:
```cs
Console.WriteLine(Num1 * Num2);
```
It's expecting that to be:
```cs
Console.WriteLine(Num1 + Num2);
```
Hope this helps! :sparkles:
