Hello kglad,
I know you have helped a lot. I am so sorry if this is going to an extent. I have exactly copied the code and did the changes you have told me, but the result seems to appear "Valid" when I input an invalid code. For instance, I am figuring out if the second, fifth, and seventh characters are numbers. I intentionally put letters instead of numbers in those specific characters to the textbox or textinput in order to test if the result will say "invalid" or "incorrect". The result does not change at all, it always appears valid.
Here's the picture for proof:

Here's the code:
// This line makes the button, btnCheck wait for a mouse click
// When the button is clicked, the displayCheck function is called
btnCheck.addEventListener(MouseEvent.CLICK, displayCheck);
// This line makes the textinput wait for a mouse click
// When this component is clicked, the clearLabels function is called
txtinCode.addEventListener(MouseEvent.CLICK, clearLabels);
// This is the displayCheck function
// e:MouseEvent is the click event experienced by the button
// void indicates that the function does not return a value
function displayCheck(e:MouseEvent):void
{
// declare variables
var Postal:String; // verifying if the first character is uppercase
var Postal2:String; // verifying if the third character is uppercase
var Postal3:String; // verifying if the sisxth character is uppercase
var str:String; // postal code entered by the user
// get the postal code from the user
str = txtinCode.text;
// selecting the first, third and sixth characters from the string
Postal = str.charAt(str.indexOf("") + 0);
Postal2 = str.charAt(str.indexOf("") + 2);
Postal3 = str.charAt(str.indexOf("") + 5);
// verify that the postal code entered by the user is valid or invalid
if (Postal.toUpperCase() == Postal && Postal2.toUpperCase() == Postal2 && Postal3.toUpperCase() == Postal3)
{
lblDescription1.text = "Valid postal code.";
}
else if (Postal.toLowerCase() == Postal)
{
lblDescription1.text = "Invalid postal code";
lblDescription2.text = "First character is incorrect";
}
else if (Postal2.toLowerCase() == Postal2)
{
lblDescription1.text = "Invalid postal code";
lblDescription2.text = "Third Character is incorrect";
}
else if (Postal3.toLowerCase() == Postal3)
{
lblDescription1.text = "Invalid postal code";
lblDescription2.text = "Sixth character is incorrect";
}
}
// this validate if the second, fifth, and seventh characters entered by the user is a number
function code_checkF(s:String):int{
var a:Array = [1,4,6]
for (var i:int = 0; i < a.length; i++){
if (!number_checkF(s.indexOf("") + a)){
return i;
}
}
return -1;
}
function number_checkF(n:Number):Boolean{
if (isNaN(n)){
return false
}else{
return true
}
}
// This is the clearLabels function
// e:MouseEvent is the click event experienced by the textInfrput
// void indicates that the function does not return a value
function clearLabels(e:MouseEvent):void
{
lblDescription1.text = "";
lblDescription2.text = "";
txtinCode.text = "";
}
