Code run extra time on each level (Multilevel windows type Tree Menu)

[youwh]

I’m trying to create a windows type Tree Menu, but with the new level shown on side rather than below. I’m still experimenting the best way to do it, and currently my idea was to have each new level to be load into the clicked button MC, so that I can have a easier way to detects the overall height/width, and who its related to. (Not sure is it the best way to do it).

Anyway, back to the topic. The code I wrote adds in a new level into the clicked MC. And I have a ‘+’, ‘-’, ‘’ button for each link, and it works like how it would in a windows.

The problem I face is, the link I clicked, the changes of the ‘+’/’-’ button would skip a layer to change for the opening or closing of a new layer.

And the most important part is, it keeps on adding extra level (same position, overlapping) at each level I clicked.

Example:

[LIST=1]
[]1st layer clicked, add 1 new level / ‘+’/’-’ work
[]2nd layer clicked, add another 1 new level / ‘+’/’-’ don’t work
[]3rd layer clicked, add 2 new level (overlapping) / ‘+’/’-’ work
[]4th layer clicked, add 3 new level (overlapping) / ‘+’/’-’ don’t work
[*]etc.
[/LIST]
I don’t know where gone wrong that makes it add extra level. Please help!
