NullReferenceException MVC4 C# Most likely beginner fail

I have been following

http://pluralsight.com/training/Courses/TableOfContents/mvc4-building

to learn some MVC C# for my Company, btw completely amazing Video.

I am populating a View with a SQL source.

In Debug I can definitely tell all my connections work, and I get to my foreach loop that should display all the data in that table

On my @Foreach( var item in Model ) it throws the NullRefException on my Model... here's the code I have

this is my complete view

@model IEnumerable<OilNGasWeb.ModelData.Clients>

@{
    ViewBag.Title = "CLS-Group";
}


@foreach(var item in Model)

{
    <div>
        <h4>@item.Client</h4>
        <div>@item.Address</div>
        <div>@item.City</div>
        <div>@item.State</div>
        <div>@item.Zip</div>
        <div>@item.ContactName</div>
        <div>@item.ContactEmail</div>
        <div>@item.County</div>
        <div>@item.Authorized</div>
        <hr />
    </div>
}

So I'm thinking it is instantiated here 

@model IEnumerable<OilNGasWeb.ModelData.Clients>

but just incase I was wrong maybe it's instantiated in the Home controller in the Index Action?

 public ActionResult Index()
    {
        var Model = _db.Clients.ToList();

        return View();
    }

Please help me figure out why it's throwing this exception thanks. I wouldn't think you needed more code. but if you do let me know what M , V , C to post for you, as said above the data part works great.

public ActionResult Index()
{
    var model = _db.Clients.ToList();

    return View(model);
}

You need to pass the model to the view, otherwise it will be null.
