C# keep common functions in seperate cs file can't find namespace

Question

First off I'm only creating this question because I can't make comments in the question that has nearly all the info I need. Here is that question so I don't have to duplicate more than I have to:

Keep common functions in separate cs file? (C#)

So I followed the info Jonesopolis gave in his answer, but it just throws me an error saying it can't find the namespace on the using GeneralStuff; line.

This is the contents of the cs file I would like to use the function from:

using UnityEngine;
using System.Collections;

namespace GeneralStuff
{
    public static class GeneralStuff
    {
        /// <summary>
        /// Creates a Unity color object using values 0-255
        /// so getting the color right is easier
        /// </summary>
        /// <param name="r"></param>
        /// <param name="g"></param>
        /// <param name="b"></param>
        /// <returns></returns>
        public static Color setColor(float r, float g, float b)
        {

            if (r != 0)
            {
                r = r / 255f;
            }

            if (g != 0)
            {
                g = g / 255f;
            }

            if (b != 0)
            {
                b = b / 255f;
            }

            Color color = new Color(r, g, b);

            return color;
        }

    }
}

This cs file is in the same folder as the cs file I would like to use this function in. Yes it is a script in Unity project in case that is relevant. I missing something, but I can't figure out what. Can someone help?

In the file where you want to use the methods of this static class add the _using GeneralStuff;_ at the beginnng of the file — Steve, Aug 13 '16 at 16:32
I have that it is where the error is thrown. Sorry about not having that in the question I always notice the stuff I missed after I post it. — Eegxeta, Aug 13 '16 at 16:34

In your second file, you have to have a using statement for the namespace you wish to use:

[[ other-file.cs ]]

using GeneralStuff;

namespace SecondFile {
    public class SecondClass {
        public SecondClass() {
            var something = GeneralStuff.setColor(0f,0f,0f);
        }
    }
}

EDIT: You'll also need to include it in the current project. From this SO answer:

Right-click project and select "Add -> Existing Item"

Navigate to the file you want to add as a link, and select it.

Look at the "Add" button at lower right of the "Add Existing Item" dialog. It has a little drop arrow.

Click that drop arrow. Select "Add as link".

@Eegxeta See the edit - hopefully that solves your issue. – Nick Bull Aug 13 '16 at 16:39 — Nick Bull, Aug 13 '16 at 16:39
