Hi Friend,

Try the following code:

<html>
<head>
<script>

function hide(){
var combo1 = document.getElementById("combo");
var val = combo1.options[combo1.selectedIndex].text;
if(val=="Hide"){
document.getElementById('x').style.visibility='hidden';
}
else{
document.getElementById('x').style.visibility='visible';
}
}
</script>
</head>
<select id="combo" onchange="hide();">
<option value="Test1">Test1</option>
<option value="Test2">Test2</option>
<option value="Hide">Hide</option>
<option value="Test3">Test3</option>
</select>
<input type="text" id="x">

Thanks
