Re: Add Listbox

Hi silvia21,

There are a couple of problems with your javascript. You haven't declared the variables (option & txt) and there was an error with the way you were referring to your controls. Also you hadn't put a backslash in your closing <script> tag.

If you change your javascript function to the following:

Code: ( text )

<script type="text/javascript">
function addBank()
{
var option = document.jaldi.lender.options[document.jaldi.lender.selectedIndex].text
var txt=document.getElementById('bank');
txt.value=option;
}
</script>

It should work for you. Let me know how you get on.

Hope this helps,

Dr B
