Copying forms in Admin Order Entry

Hello. I am trying to edit the admin create order page (sale/order/add) so that input-firstname gets copied in input-payment-firstname, input-payment-firstname to input-shipping-firstname, etc by just pressing the next button.
I put in tpl
<script>
function copy()
{ var input-firstname = document.getElementById(input-firstname);
var input-payment-firstname =document.getElementById(input-payment-firstname);
input-firstname.value = input-payment-firstname.value; return false; }
</script>
and call the function on the button with onclick.
Nothing happens however. Any help?

Is this your pseudo code or real code? If this is pseudo code, please share real code. If it is real code, it does not make any sense.
