MVC3 Razorview syntax

I have the following in my view:

    @{ var index = 0; }
    @foreach (var item in Model)
    {
    ...
    @{ 
         index += 1; 
     }
    }

but i get

No overload for method 'Write' takes 0 arguments

what gives? thanks

i believe it should be...

@{ var index = 0; }
@foreach (var item in Model)
{

     index += 1; 

}
