Need help with custom HUD message

Hey! Need your advise how to do message with custom text that triggers by button. Player push the button and se simple message with his nick, map code and his lifetime score (like on screenshot)
savepoint device is already set up, need help only with message

Maybe this would be of some help. It shows how to create a on-screen button to trigger any device; in your case, it could trigger a HUD Device with your message or whatever way you want to generate the message.

That might also just be a Popup Dialog Device and not a HUD Message Device
