I have a button component “runCalc\_button” labeled “Caclulate” within a movie Clip “inputScreen\_mc”.

I’m trying to access the button’s properties from the Root, but I’m getting back “undefined.”

Here’s my code:

```auto

_root.attachMovie("inputScreen_mc", "inputScreen_mc", 200);
trace(_root.inputScreen_mc.runCalc_button);
trace(_root.inputScreen_mc.runCalc_button.label); 

```

the first “trace” returns “\_level0.inputScreen\_mc.runCalc\_button” as it should.  
the second returns “undefined.”

Anyone know why? Shouldn’t it return “Calculate.”
