Razor view engine, how to write inbetween html

i have some problem with a razor syntax. I would like to know how to write inbetween html.. see this sample..

<ul>
    @foreach (var x in Model) {
        <li>
            @x.Subject - Tags:&nbsp;

            @if (x.Tags != null)
            {

                foreach (var t in x.Tags)
                {
                    @t.Name
                }
            }
            else
            { 
                No tags
            }
        </li>
    }
</ul>

I should be able to write "No Tags" but this doesnt work… No tags seem included in the code (which is not what i want.

Thanks
