So.. I've been trying to have objects/symbols appear in relation to a button.
I guess the easiest way to explain it is.. I'm trying to create something similar to a volume meter on your TV set.
When you click button a.. a box will appear.
Like so.. 
If you keep pressing button a.. more boxes will appear.
Like so..      
However if you press button b.. the inverse will happen.
The boxes will disappear one by one until there aren't anymore left.
So I tried to figure out a way using the get.symbol command and the ++ but just couldn't get them work..
Wondering if someone could point me in the right direction..
Oh and if possible I'd like to ease in each "appearance"..
I uploaded what I have so far here.. maybe it'll better explain what I'm trying to do..
Thanks for your help!
