Domo Arigato Mr. Roboto. <br>

How many times have you wanted to not clean up your room, or do anything at all?

Do you remember the last time you wished you had a bodyguard or a helper robot?

<br>Well now you dont have to!<br>

</p>









  <form name="joes"><br>

  <input type="radio" name="bb" value="generic">Generic Robot<br>

  <input type="radio" name="bb" value="helper">Helper Robot<br>

  <input type="radio" name="bb" value="bodyguard">Body Guard<br>

  <input type="radio" name="bb" value="killer">Killer Robot <br>

  <input type="submit" name="submit" value="submit" onclick="calculate_total(joes.bb.value)">

  </form>

</body>

</html>

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>
