Radio Button single select

How can i make it so that i can have muiltiple radio buttons, and you are only allowed to select one at a time. So that if you have A selected, and click B, it deselects A?

Thanks.

<input type="radio" name="example" value="A">Radio Button A
<input type="radio" name="example" value="B">Radio Btn. B


See the difference? Give them the same name, but change their values.

i see no code...

What do you mean?
