Activiate a textbox on dropdown selection not working in IE8

Hi,

I need to get a form to activate a textbox based on a dropdown selection. I found the below script which works fine on Firefox, Chrome and IE9+, but will not work on IE8.

Script:

<html>
<head>
<script type="text/javascript">
function checkvalue(val)
{
    if(val==="others")
       document.getElementById('color').style.display='block';
    else
       document.getElementById('color').style.display='none'; 
}
</script>
</head>
 
<body>

<select name="color" onchange='checkvalue(this.value)'> 
    <option>pick a color</option>  
    <option value="red">RED</option>
    <option value="blue">BLUE</option>
    <option value="others">others</option>
</select> 
<input type="text" name="color" id="color" style='display:none'/>
 
</body>
 
</html>

I would like this to work in IE8. Any assistance would be greatly appreciated.

Thank you.

Although valid HTML, you just need to make sure that the names of the select and input are different. Since you use the input's id in your function, I tried this (changed the name of the select) and it works ok now, tested in IE8 and Firefox:
<html>
<head>
<script type="text/javascript">
function checkvalue(val)
{
    if(val==="others")
       document.getElementById('color').style.display='block';
    else
       document.getElementById('color').style.display='none';
}
</script>
</head>
 
<body>

<select name="colorSEL" onchange='checkvalue(this.value)'>
    <option>pick a color</option>  
    <option value="red">RED</option>
    <option value="blue">BLUE</option>
    <option value="others">others</option>
</select>
<input type="text" name="color" id="color" style='display:none'/>
 
</body>
 
</html>
