Hi Everyone,

I am trying to reproduce a classic number pyramid in flash.
Its basically 3 text fields in a row with 2 text fields above them and finally a single text field at the top making a pyramid.

As you enter numbers in the bottom 3 fields the boxes above will show their addition up to the top box.

Just like this example:

If anyone could point me to a .fla file or offer any help it would be appreciated.

Cheers
Phil
