arrange->send backward not sending graphics behind

Question

I'm following instructions to make a simple background in Flash CS4 using vector graphics. I'm at the part where the book tells me to put the cloud graphics behind a hill I drew by clicking modify->arrange->send backward, however, clicking that option does not seem to do anything.

Edit: the hill and clouds are on the same "foreground" layer, my bad!

SOLUTION: I got it to work by converting the hill into a graphic symbol.

The clouds circled are supposed to be behind the hill:

Answer 1

You need to actually drag the layer that holds your clouds (next to the timeline) so that it's listed underneath the layer holding your hills.

Using send backward only applies to the children/graphics of the layer you're working on.

Just a note: looking at your layers and current graphics it seems that the blue elements are also on the layer "background". If this is the case, your clouds will disappear behind the blue also. You'll need to make an additional layer which holds just the blue (sky and water?) and place that below the clouds AND the hills.
