Something like this should work as long as you have added the extra parameter on the macro in Umbraco:

         <umbraco:Macro ID="Macro2" Test="<%Session["myVariable"].ToString(); %>"  runat="server">

        </umbraco:Macro>

Alterntatively you can also get fields from the node that is rendering if you do something like this:

         <umbraco:Macro ID="Macro2" ToEmail="#[email]"   runat="server">

        </umbraco:Macro>

So in this example I have an Event master page and an Event macro which has an extra parameter called ToEmail and as the event node is being rendered the Umbraco checks the node for a field called 'email' and passes it into the macro.

Hello, 

<umbraco:Macro ID="Macro2" Test="<%Session["myVariable"].ToString(); %>"  runat="server">

        </umbraco:Macro>

Does not work.

Parser Error Message: Server tags cannot contain <% ... %> constructs.

Anybody has a suggestion how to pass a session variable into an umbraco macro?

TIA,
