Exactly, I'm not sure what you're trying to do so this may or may not help.

First of all, your missing a }

Now, I'm gonna guess and say that you want to alert the number 1 if any radio button is selected, else you'll alert the number 0 if not. To do this, you don't need to have the variable a as a parameter.

Here is the code that'll do that:

function vote() {
var a = 0;
for(i = 0; i < document.form1.bad.length; i++) {
if(document.form1.bad[i].checked == true) {
a = 1;
}
}
alert(a);

}

and change the input button below to:
<input type="button" value="Abstimmen" onClick="vote()">

If this is not what you were looking for then oh well :)
