newbie, session problem

[Jeff]

hi

asp.net 3.5

in a webpage I add a value to the Session:
Session["Name"] = txtName.Text;

In another page i try to access this value:
string name = (string)Session["Name"];

but name gets nothing, or ""

In the end i wants to transfer username, 2 datetime values, mobilenr, email,
and a few other values... so I thought it wasn't place for it in the
querystring...

any ideas?
