Not able to get the data from variables contained in more than 1 mxml file

Question

I have got 5 Bindable Public integer variables in total in 5 mxml files (Pages). Each variable is assigned it's value in a Public function in each of the mxml files.
What I need to do is add up the values of the 5 variables. The way I approached this was to create a public function add5Variable in my main mxml file (Page1) as shown below.
[Bindable]
public var varTotal:int = 0;
public  
varTotal = (variableP1 +
Page2.variableP2 + Page3.variableP3 + Page4.variableP4 + Page5.variableP5);
return(varTotal);
I have got a TextInput field on Page5 where I display the varTotal. The function add5Variable is called when moving from Page to Page.
The results I am getting is that the varTotal will always be the value of variableP1. When I tried some debugging in Flex Builder it showed me that the other 4 variables had a value of 0.
Why is this the case and do you have any suggestions on how I can get the correct total for varTotal?
Thanks
function add5Variable():int {

The code below looks correct. Is that the expected behavior of your app?

public function test():void {
if (Number(TextInput2.text) == 1 || Number(TextInput2.text) == 2)
ValueP2 = 1;
totalValue = grossValue + ValueP2;
else if (Number(TextInput2.text) == 3 || Number(TextInput2.text) == 4) {
ValueP2 = 5;
totalValue = grossValue + ValueP2;
else if (Number(TextInput2.text) == 5 || Number(TextInput2.text) == 6) {
ValueP2 = 9;
totalValue = grossValue + ValueP2;
trace("totalValue "+totalValue);
finalValueP2(totalValue);
public function finalValueP2(tVP2:int):int {
var tallyP2:int = 0;
if (tVP2 < 3)tallyP2 = 1;

if (tVP2 >= 5 && tVP2 <10)tallyP2 = 3;
finalTotalP2 = tallyP2 * 7;
trace("finalTotalP2 " +finalTotalP2);
return(finalTotalP2);
