I would be so greatful if someone can help with this. I've been sitting for days to find my mistake but my inexperience really holds me back here 
In my spelling game I have letters falling out of the sky - players have to click on them. I tested one letter in this swf. It works as I planned but it was only one letter hard coded.
So now I have many levels and I added the letters needed for each level in arrays generated through a loop. They trace correctly, but they do not show up in this swf.
I'm sure I am just missing a bit of code in the function or didn't addChild correctly. I doubble checked that the missing MC is not behind the background by turning the backgroung off, but it is not that.
Where am I going wrong?
Here is the relevant code:
