Pascal,

Pretty much.  Just a couple of things to remember:

session_start() must be called before ANY output to the client.  This
includes <!DOCTYPE...>, <HEAD...> and even blank space.

This must be done on EVERY page which uses $_SESSION values.

And, of course, you must store the value in the $_SESSION, also.

And you should check to see if the value is set before using it (i.e.
the first time through it may not be set); if not,  you should supply a
default value.

As for whether your jQuery code will work or not - try a javascript
newsgroup.  But the PHP code looks OK.
