    How do I build this?

    Not sure how I would build this but I want to make a javascript that will generate text based on a switch. It will also need to generate text for radio buttons based on the selected switch variable as well. Basicly I want to build something to generate a question and multipal choice answer. Ive got this code so far with a little help from another post.

    Code:
     <script type="text/javascript">
    	function myfunction(obj)
        {
            var mycolor = obj.value;
    
            switch (mycolor) 
            {
                case "Blue":
    				alert("Blue");
    				break;
    				
    			case "Red":
    				alert("Red");
    				break;
    				
    			case "Green":
    				alert("Green");
    				break;
    				
    			case "Yellow":
    				alert("Yellow");
    				break;
            }
        }
    	</script>
    </head>
    <body>
    <div id="choices" >
    	<input type="radio" name="group1" onclick="myfunction();" value="Blue" />Blue <br/>
    	<input type="radio" name="group1" onclick="myfunction();" value="Red" />Red <br/>
    	<input type="radio" name="group1" onclick="myfunction();" value="Green" />Green <br/>
    	<input type="radio" name="group1" onclick="myfunction();" value="Yellow" />Yellow <br/>
    </div><br/>
    So I guess the best way to do it would be make a new function to generate the Q/A thing and put the text inside the form but how do I do that and would that be the best way?

    I made this but it errors for some reason:

    Code:
    <script type="text/javascript">
        function GenQuestion()
        {
            var intQuestion = Math.floor(Math.random()*11)
    
            Switch(intQuestion)
            {
                case 1:
                document.write("Case 1");
                break;
    
                case 2:
                document.write("Case 2");
                break;
    
                case 3:
                document.write("Case 3");
                break;
    
                case 4:
                document.write("Case 4");
                break;
    
                case 5:
                document.write("Case 5");
                break;
    
                case 6:
                document.write("Case 6");
                break;
    
                case 7:
                document.write("Case 7");
                break;
    
                case 8:
                document.write("Case 8");
                break;
    
                case 9:
                document.write("Case 9");
                break;
    
                case 10:
                document.write("Case 10");
                break;
            }
        }
    </script>
    
    GenQuestion();

    <script type="text/javascript">
    function GenQuestion()
    {
    var intQuestion = Math.floor(Math.random()*11)

    switch(intQuestion)
    {
    case 1:
    document.write("Case 1");
    break;

    case 2:
    document.write("Case 2");
    break;

    case 3:
    document.write("Case 3");
    break;

    case 4:
    document.write("Case 4");
    break;

    case 5:
    document.write("Case 5");
    break;

    case 6:
    document.write("Case 6");
    break;

    case 7:
    document.write("Case 7");
    break;

    case 8:
    document.write("Case 8");
    break;

    case 9:
    document.write("Case 9");
    break;

    case 10:
    document.write("Case 10");
    break;
    }
    }

    GenQuestion();
    </script>

    1. javascript is a case sensitive language. so Switch is not same as switch
    2. You are making call to GenQuestion() outside of javascript block thats why it does not run,
