I got as far as...

<umbraco:Macro runat="server" language="razor">
  @Model.NodeTypeAlias
  {
    <h2>@Model.contentHeader</h2>
  }
</umbraco:Macro>

Something along the lines of below should work. Razor is clever enough to work out when code stops and mark up begins.

@if (Model.NodeTypeAlias == "Home")
{
    <h2>@Model.contentHeader<h2>
}

Nope doesn't work!

But the code I posted does work, so the issue is with the @if?

Very confusing, for such a simple thing ;)

Does @Model.NodeTypeAlias work? should it be @Model.GetProperty('NodeTypeAlias').Value() ?

I've never used inline razor before. Only is .cshtml files. Maybe remove the @ so try this:

if(Model.NodeTypeAlias=="Home")
{
  <h2>@Model.contentHeader</h2>
}

Okay so, 

@Jay - yep it works!
@Jeroen - that didn't work, but the @Model.contentHeader bit did work...

So I thought, maybe if I add a @ infront of the if...

and it worked! (:

<umbraco:Macro runat="server" language="cshtml">
@if(Model.NodeTypeAlias=="Home")
{
  <h2>@Model.contentHeader</h2>
}
</umbraco:Macro> 

Isn't your answer the same as my post? Razor is a combination of HTML and C#. If you're using the @ it will enable you to use C# code. This blog might help :) http://weblogs.asp.net/scottgu/archive/2010/07/02/introducing-razor.aspx

@Lau glad you figured it out :)
For the Razor engine to understand you are typing Razor you need to prefix the if with @ so it knows it's code and say not just normal text or HTML.

I recommend reading over Scott Gu's post on an introduction to Razor so you can pick up the syntax

Thanks for all the help! Not quite sure what was going wrong, as Jeroen rightly said, you got it earlier! Thanks again, Laux
