does Level() do anything?

enclosed is the complete rdl for a report that has a table, contains groups
and calls the level function.
Returns the current level of depth in a recursive hierarchy. it looks like
the recursive part does not work?
what am I missing here?

</Report>Level function is for recursive hierarchies, which are tables that link back
to themselves. If you create a table such as...
CategoryID CategoryParent
1 0
2 1
3 1
4 0
5 4
6 4
7 4
8 2
9 2
10 2
11 9
12 10
13 12
and set your query to be
Select t1.CategoryID, t2.CategoryID as Subordinates from Sometable t1 left
outer join Sometable t2 on t1.Categoryid = t2.CategoryParent
Then you could use the level function to tell you how far each category node
is nested.
