Count-Function in Message Mapping

Question

Hey, trying to map following structures:
message
-m1
--m11
-m2
--m22
-m3
--m33
to
message
-m1
--m11
-m2
--m22
-m3
--m33
-f1
--countItems
The nodes m1,m2 and m3 can appear 1..unbounded. In target structure I would
like to have the numbers of all nodes (m1,m2,m3).
For example: In this source structure m1,m2,m3 appear only one time. In the
field countItems I would like to have the number 3.
I tried the count function, but it could only count the structure where I used it (in
this case: f1).
How can I count the above-mentioned nodes?
thanks
chris

Hey,
thanks for your answers.
But I still couldn't understand how to do this. I open the message mapping for field f1, but the count function could only be set on an target-element, so where to set the counters for m1,m2,m3? Do I have to insert extra fields under m1..m3?
If I do the counter would increment with every node, so if I have two times m1, in second tree of m1 a two will be insert. If I use the add function, only for these two tree the result would be three!

Is this just one UDF? From where he knows, which nodes he have to count, if I have more than m1..m3, but only want to count this three?
@ sasitharan
same problem as mentioned above:
this doesn't work:
m1--count---\
I can't use m1 as input for count! Or do I have a wrong count function?
<b>....au damm, answered my own question. Of course. I use COUNTER and you use
COUNT!!!!!!!!!!!! I will try this with COUNT!!</b>
thanks
