Problem of defining value to a textfield in MovieClip

Question

hello,dear everyone
there is problem that realy confused me.that is the
textfield(or other display objects) in MovieClip can't be defined
when i jumpto that frame.check these simple code:
mc.stop()
function goNext(evt:Event){
mc.nextFrame()
dosth()
function dosth()
if(mc.currentFrame==2)
mc.mytext.text="hello"
nextBT.addEventListener("click",goNext)
the mc is a simple MC that have 2 frames,and the textfield
object is in the second frame.
and what i try to do is when i clicked the button,the mc
jumpto the second frame.and i define a value to that textfield.but
it's failed when i try to do like that.
as i debug the program.i found that when i define the value
to the textfield,that textfield is a Null Object(should be the
TextField object).not only the textfield not work,but also other
elements such as Button objects.
so,i am thinking that must because the objects are too late
to initialized before they be used.maybe there are some event can
tell me that all elements has been initialized,as i can use them
then.what do you think,my friend?

Answer 1

If all of the code you have is in the first frame, then it
has processed long before anything ever moved to the second frame.
What you could try is to have a variables layer that extends
both frames, and assign the value of the textfield text to that
variable. Make the textfield associate with that variable (in the
properties section for it), So when the movieclip moves to the
second frame the text field should automatically acquire the
variable value.
I may not have interpretted your problem correctly, so you
might have to clarify things if I missed the target.
