Passing Session variables (ASP.NET)

Hi,

I've been working on a site for quite a while and am a fair way in using Javascript. However I thought I'd check out a bit of asp.net as it has quite a few functions that seem easier to implement than in Javascript.

I have a login page created using the built-in server behaviours that sets a session variable in Javascript using the following line of code:

Session("MM_Username") = MM_valUsername;

This variable is avalable to all other javascript pages and I can disply the variable on a page by placing this lin eof code within the HTML:

<%= Session("MM_Username") %>

However the one page that I have created using vb.net will not display the variable. The code I'm using is this:

<% =Session("MM_Username")%>

Is there a reason for this or am I just doing something wrong?

Thanks in advance

Dan
