Looping errors

Hello, I need some help with my code as it has 5 errors in which I do not know how to fix. My assignment has to look like this:

Here are the errors:

Here is the code:

//This line makes the button, btnPrint wait for a mouse click  //ERROR 5000 IS APPARENTLY HERE

//When the button is clicked, the countNumbers function is called

btnPrint.addEventListener(MouseEvent.CLICK, countNumbers);

function countNumbers(e:MouseEvent):void

{

var Year:uint = 1;

var Amount:Number;

var Interest: Number;

var Total: Number;

var NYear: uint;

Amount = Number(txtinInvest.text);

Interest = Number(txtinRate.text);

NYear = uint(txtinYears.text);

while (Year <= NYear)

{

lblYear.text += String(Year) + "\r";

Year++;

}

do

{

lblAmount.text += Amount.toFixed(2) + "\r";

lblAmount.text += String(Amount) + "\r";

Interest /= 100 *= Amount += Amount;

}

while (1 < Amount)

while (0 < Interest)

{

lblInterest.text += Interest.toFixed(2) + "\r";

lblInterest.text += String(Interest) + "\r";

(Interest /= 100 *= Amount) += Amount *= (Interest /= 100); //ERROR 1105 IS HERE

}

while (0 < Total)

{

lblTotal.text += Total.toFixed(2); + "\r";

lblTotal.text += String(Total) + "\r";

Amount + Interest;

}

}

I got the Year column to work but not the others. Kindly edit my code to make it look like the program.
