Glad you worked it out.
One thing you should do is make sure a session variable exists before using
the session variables.
When I first loaded the page I received an error, after I refreshed the
error went away.
You should cfparam the variables to a default first, otherwise they wont be
set until after you call the ajax request.
The success: function(){} is used to call back the data from the ajax
request, you could use those to dynamically set a div to the variable
returned.
Error Occurred While Processing Request
Element SCREENSIZE.WIDTH is undefined in SESSION.
