is it working like you expect it to work? I see you misspelled this part "getRamdon " , so thats why I ask if it works?

I have a question: What's the idea of having the same code in different functions and just different parameter? You saw that you have a mistake "getRamdon" and after the second function you call:

alert(getRandom(3));

OR you are just calling the first function a second time?! I don't get it. Isn't it better to do it:

function getRandom(num){
    return Math.floor(Math.random() * num ) + 1;
}
var upper = getRandom(100);
var lower = getRandom(3);
alert(upper);
alert(lower);

If you don't need the variables you can just:

alert(getRandom(100));
alert(getRandom(3));

Hope I helped :)
