Interchanging variable's values within nested MC

[quequen]

I have trouble with this:
A button in _root sends a variable's value to an MC, like this:
setvar (_root.mymc01.TIPOBARCO) = "LIMBO";

I've put a dynamic text box into mymc01 to show TIPOBARCO's value. When calling _root.mymc01.TIPOBARCO I foun it has the new value (in this case, "LIMBO"), but the dynamic text box doesn't show it.

Why? can you help?

is your text box have a variable name of TIPOBARCO ... not the instance name .... but the variable field ... ?

yes, my dynamic text box has TIPOBARCO as variable name. I havent tried to use instance names for text box's yet.
And I put a button into mymc01 who sends TIPOBARCO's value to a dynamic text box into _root and it works correctly, but the dynamic text box in mymc01 doesn't show any value.

well well, now I 've got the problem (and I'm waiting solution, please):
when you apply a mask over a layer having Dynamic Text box or Input Text box, this box just dissapear.
If you quit the mask or if you turn the Dynamic Text box into simple Static Text box, then text box reapears normally.
I'll appreciate any help with this! :)
