Question

I am trying to determine what the total is equal to and then do a job pertaining to each selection. My first selection is if the total is 2, 3, or 12, then you lose. If it is a 7 or a 11, you lose. Anything else the point is established. First my code looked like this, but every single time, it went to else. The total is being calculated through 2 random numbers added together using this function:

   Math.floor(Math.random()*6+1);

function game()
 {
if(total==2 || total==3 || total==12)
    {
        alert("You lose. Please start a New Round");
    }
if(total==7 || total==11)
    {
        var temp= 2 * bet;
        alert("You win $" + temp);
    }   
else 
    {
        alert("Point Established. Roll again.");
        var point=total;
        setTimeout(rolldice2,3000);
    }
 }

Then I changed it to this:

 function game()

 {
if(total==2 , 3 , 12)
    {
        alert("You lose. Please start a New Round");
        return;
    }
if(total==7 , 11)
    {
        var temp= 2 * bet;
        alert("You win $" + temp);
        return;
    }   
else 
    {
        alert("Point Established. Roll again.");
        var point=total;
        setTimeout(rolldice2,3000);
    }
 }

But it just says you lose no matter what. Then I finally took out return. It does the first 2 and not else. I want to be able to choose one- depending on what the variable total is equal to- and then perform its jobs and then leave the function.

In your case total variable is undefined

Pass total to your function and do a switch statement

 function game(total)
 {
    switch(total)
    {
        case 2 : 
        case 3 :
        case 12 : {
                    alert("You lose. Please start a New Round");
                    return;
                  }
        case 7 : 
        case 11 :
                 {
                    var temp= 2 * bet;
                    alert("You win $" + temp);
                    return;
                 }   
        default : 
                {
                    alert("Point Established. Roll again.");
                    var point=total;
                    setTimeout(rolldice2,3000);
                }
    }
 }
