Textbox/Label - Converting digits to words

Hi all,

I have a textbox in a form that receives only digits. but my challenge now is to drop a label in front of that textbox so that when the user type in any digit in the textbox, the label with get the value of that digits in words.

That is, if the value in the textbox is 99, the label will automatically be"Ninety nine". And if the textbox value changes, the label value automatically change as well.

I need someone to put me through on this.

Thanks in advance.
