Show more code. Is that a click event?

it is not click event
it is after select event of tree view

You are ASSIGNING the value...NOT accumulating it!

What is being returned is the number of nodes in the last item scanned.

You need a recursive (yes I know it can be flattened!) way to count the nodes...
