    Problem passing an argument...

    I started Javascript yesterday.
    I am trying to make the function Captain Obvious simply say what button you are pressing in an alert box, but after I click the button, nothing happens at all, no error message or anything. I have tried it with no argument inside the script call, and then it sort-of works. The alert box comes up saying: "You have clicked on a button that says "undefined"." I am pretty sure that means that I am having a problem passing the argument when I call it, but to be honest I have no clue lol
    Code:
    <head>
<script type="text/javascript">
function CaptainObvious('choice')
{
	alert("Captain Obvious:You have clicked on a button that says ''"+choice+"''.");
	alert("Just fulfilling my public duties.")
}
</script>
</head>
<body>
<form>
<input type="button" value="Apple" onclick=CaptainObvious("apple")>
</form>
    Any ideas?

    It's a matter of the quotes.
    Code:
    <html>
<head>
<script type="text/javascript">
function CaptainObvious[COLOR="Red"](item)[/COLOR]
{
	alert("Captain Obvious:You have clicked on a button that says[COLOR="Red"] "+ item);[/COLOR]
	alert("Just fulfilling my public duties.")
}
</script>
</head>
<body>
<form>
<input type="button" value="Apple"[COLOR="Red"] onclick="CaptainObvious('apple')" [/COLOR]>
</form>
</body>
</html>

      You are getting an error message, just check the error console. GIYF
