Passing text to new text fields

Question

Hello everyone. I've been going crazy with this trying to
figure out why my variable isn't 'passing to another frame on the
same scene. I declared a variable ( var sStudentParagraph:String =
mcStudentWrite.text ). Where the "mcStudentWrite.text is the text
inside an input text box.
I trace the value of it after I click a submit button I made,
and it shows me the value of whatever I happened to type in the
input text box. The user is then lead to a screen witih a new
dynamic text box that should display what they typed on the
previous input text box. ( mcStudentWork.text = "you typed " +
sStudentParagraph; ). But nothing loads into the "mcStudentWork"
dynamic text box, I just get a value of undefined...
I've worked with with numeric values before for scoring tests
etc, and having the value load into a dynamic text box revealing
their score, and tha'ts worked fine. I'm at a loss as to why this
isn't working for me. Any insights will be most appreciated.

Answer 1

So future text boxes have to be present on stage in order for
them to work in the future? I had never realized this. The
mcStudentWork text box is the new textbox that should be displaying
the input text from the previous user submission, but it's on the
stage on the frame in which it's needed to be seen, but not prior
to that. The only text box the user sees prior to that is the
StudentWrite text box.
But when I did my test scoring dynamic text box I never had
to do that.
I used a variable declared at an earlier time, on a different
frame, and when the score box needed the number of correct answers
it displayed the correct number just fine.
I'm seeing the undefined when I trace the "sStudentWork"
variable when I'm on the frame that has the dynamic input text box
"mcStudentWrite". For some reason it seems like it's forgetting the
variable from one frame to the next. I don't have the variable
declaration inside a button function, it's the first thing I have
written after the stop command.
