The name 'InitVariables' does not exist in the current context

I'm a C# newbie. I'm getting the above error in the section of code below:
namespace SSTW
{
    public partial class FormGameType : Form
    {
        public FormGameType()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            InitVariables.GameType = 1; //Regular game
        }
    }
}

The other relevant code snippets are:
namespace SSTW
{
    class InitVars
    {
        public int GameType{ get; set; }
    }
}
namespace SSTW
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            InitVars InitVariables = new InitVars();
Any help would be appreciated.
