fra select-box til text box eller hidden felt

Her er den kode jeg arbejder med lige nu.

<form name='myForm'>
<SELECT NAME='AddressBook' multiple size="10" ONCLICK="fnFill(document.myForm.AddressBook)">


<OPTION Label='Anantharaman'>Narayanan9</OPTION>
<OPTION Label='Chetan'>Patil</OPTION>
<OPTION Label='Chetan'>Shah</OPTION>
<OPTION Label='Nitin'>Gupta</OPTION>
<OPTION Label='Shankar'>Jha</OPTION>
<OPTION>Other</OPTION>

</SELECT>
<BR><BR>

Selected Names &nbsp; <INPUT name=txtNumber type='text' >
<SCRIPT LANGUAGE="JavaScript">
  function fnFill(field)
  {
    val strSelection = document.myForm.txtNumber.value +
      document.myForm.txtNumber.value=field.options[field.selectedIndex].value;
  }
</SCRIPT>
</form>

hmm

ændre ONCLICK til ONCHANGE

.. prøv det ..

hidden-input OG textarea ?-)
