How do I move text between frames?

In my project I have 24 different frames with different visual content. On frame one I have a dynamic text box that is supposed to display a currently selected list item. On frame 24 is the selection list with 4 options to choose. I am wanting the content of a different box to be assigned back to frame 1 when pressed on frame 24. My code for both frames is below. Any suggestions are appreciated.

Frame 1

var stateLast: int = 1;

var SChem: String = 'Chem1';

var c1: String = 'Chem1';

var c2: String = 'Chem2';

var c3: String = 'Chem3';

var c4: String = 'Chem4';

var modeLast: int = 1;

SelectedChem.text = SChem;

function SelectC1(event:MouseEvent): void {

  SChem = c1;

  SelectedChem.text = SChem;

  trace(SelectedChem);

}

function SelectC2(event:MouseEvent): void {

  SChem = c2;

  SelectedChem.text = SChem;

  trace(SelectedChem);

}

function SelectC3(event:MouseEvent): void {

  SChem = c3;

  SelectedChem.text = SChem;

  trace(SelectedChem);

}

function SelectC4(event:MouseEvent): void {

  SChem = c4;

  SelectedChem.text = SChem;

  trace(SelectedChem);

}

Frame 24

Chem1.text = c1;

Chem2.text = c2;

Chem3.text = c3;

Chem4.text = c4;

HomeBtn.addEventListener(MouseEvent.CLICK, GoHome);

sc1.addEventListener(MouseEvent.CLICK, SelectC1);

sc2.addEventListener(MouseEvent.CLICK, SelectC2);

sc3.addEventListener(MouseEvent.CLICK, SelectC3);

sc4.addEventListener(MouseEvent.CLICK, SelectC4);
