I see. It might be a better solution to check the two chosen numbers against each other. Whichever is bigger you than use as the upper in your random number generator.

var upper, lower, aRandomNumber;

function randomNum(upper, lower) {
    return Math.floor((Math.random() * (upper - lower)) + 1);
}



var num1 = prompt("Please Pick Any Number");
var num2= prompt("Please Pick A Second Number");




while (num1=num2) {
    num2= prompt("Please Pick A Number That is Not The Same As The First");
}

if (num1 > num2) {
   upper = num1;
   lower = num2;
} else {
   upper = num2;
   lower = num1;
}

aRandomNumber = randomNum(upper, lower);   //calls the function, you can do with it as you like

You will get there and be fine. They reuse the random number generator quite a bit. When you mentioned doing the larger number versus smaller number I thought you were farther along in the courses. You are doing well just keep at it. It takes patience and sometimes watching and rewatching the same videos to understand.

Your code ends up with an endless loop that can only be exited by checking a box to stop displaying the alert boxes.

Yes I have seen it when I tried to put a smaller second number.Now it should work if you try it again.

I am not sure what the program is supposed to be doing. It has some issues. It asks multiple times for the second number. I entered 5 first, than 1 and it asks me to enter a number then bigger than the first. So I entered 8 and, it keeps asking me.

When I click cancel it prints something to screen.

It should let you to insert two values and give a random value between them.But in order to be sure that the second number is bigger than the first I have tried to insert a loop.
