Do you remember the last time you wished you had a bodyguard or a helper robot?
<br>Well now you dont have to!<br>

   <form name="joes"><br>
   <input type="radio" name="bb" value="generic">Generic Robot<br>
   <input type="radio" name="bb" value="helper">Helper Robot<br>

Try to name your checkbox with an unique name, like bb1, bb2...

If you want to capture checkbox value, try :

Code:

<script>
global_type = "generic"; // default to generic
function update_type( type )
{
    global_type = type;
}
function calculate_total()
{
document.write("Type: " + global_type);
}
</script>
...
   <form name="joes"><br>
   <input type="radio" name="bb" value="generic" onclick="update_type(this.value)">Generic Robot<br>
   <input type="radio" name="bb" value="helper" onclick="update_type(this.value)">Helper Robot<br>
   <input type="radio" name="bb" value="bodyguard" onclick="update_type(this.value)">Body Guard<br>
   <input type="radio" name="bb" value="killer" onclick="update_type(this.value)">Killer Robot <br>
   <input type="submit" name="submit" value="submit" onclick="calculate_total();">
   </form>
