Counter Animation for Showing Volume Achievment (Adobe AIR)

Hi, We have weekly office meeting in the office, where we present current target achievement as per that week. Usually we will just saying the sales increment of that week by saying numbers: 45, 46, 47, 48, and so on.. Now we would like to add little animation on the screen, showing the number increment as we press the enter/click the number. Features: - Can save the last number, so it will continue the same number on next app open. - Fireworks/celebrate animation in the background, trigger by space bar. - We want it still editable via Adobe Animate to add corporate image/branding to the counter.
