Oops, small typo.
Javascript code:
function OnEvent_Timer(Timer){
if (Timer == 'rato'){
// Set personal message
Messenger.MyPersonalMessage = 'Score: ' + Score; // Recreate timer
MsgPlus.AddTimer('rato', 10000);
}
}
The old name "score" should have been replaced by "Score". JScript is case sensitive when it comes to variable and function names.
