select box + show/hide content

I have a form where I have a dropdown box with values of yes(default selected) and no. What I want to do is if a user selects ‘yes’, then show an input box. ff they select ‘no’, then show a textarea to allow them to enter content. How can I do this?

Thanks

<head>
<script type="text/javascript">
function showhide(sel) {
if (sel.options[sel.selectedIndex].value == "no")
{sel.form.t1.style.display = "none";}
if (sel.options[sel.selectedIndex].value == "yes")
{sel.form.t1.style.display = "block";}
}
</script>
</head>
<body>
<form onsubmit="return false">
<select onchange="showhide(this)">
<option value="yes" defaultSelected>yes
<option value="no">no
</select>

@jrthor2authorMar 15.2007 — ok, just by looking at the code, I'm not sure this is exaclty what I want. My form elements are in a table, so when I select 'yes', I want to to show an input box, if I select 'no' I want to show a textarea (not an input box).

Also, my for is in a table with 2 columns, so I want to show a particular row if they select yes (which has a label and an input box), or show a row with a textarea that spans 2 columns.).

Also, when the page loads up, I don't want the input box or textarea to show at all.

will this script do that?
