Showing a textbox with an onchange event

Arc

Hi, I have a listbox that has 2 values Current Images and New Images. I want to be able to have a textbox show on the page when New Images is selected and have it disapear when the other is selected.

I know this is javascript and i know basically how to do it but i dont know how to get a textbox to show or hide. Here's what i have.

<select name="select" onchange="GetValue(list)">
                  <option selected>Current Images</option>
                  <option>New Images</option>
                </select></td>
				<script language="javascript">
				function GetValue(aList){
				var ListValue = aList.options[aList.selectedindex].text
				If (ListValue = "New Image"){
				<br> show text box
				}else{
				hide text box
				}
				}
				</script>

Any help is appreciated!😃

I don't know exactly how list boxes work. This is a drop-down menu:

<?php
$action = $HTTP_GET_VARS['action'];
$actions = array('currentimages' => 'Current Images', 'newimages' => 'New Images');
$php_self = $HTTP_SERVER_VARS['PHP_SELF'];

if (!$action) {
  $action = 'currentimages';
}

$html = "<form action=\"$php_self\" method=\"get\">\n";
$html .= "<select name=\"action\" onchange=\"window.location=('{$php_self}?action=' + this.options[this.selectedIndex].value)\">\n";

foreach ($actions as $actions_key => $actions_value) {
    if ($action == $actions_key) {
      $html .= "<option value=\"{$actions_key}\" selected>{$actions_value}</option>\n";
    } else {
      $html .= "<option value=\"{$actions_key}\">{$actions_value}</option>\n";
    }
}
unset($actions_key, $actions_value);

$html .= "</select></form>&nbsp;&nbsp;\n\n";

if ($action == $actions['newimages']) {
  $html .= "<form action=\"$php_self?action=newimages\" method=\"POST\">\n";
  $html .= "<textarea name=\"comments\" rows=4 cols=50>Type stuff here!</textarea>\n";
  $html .= "</form>\n";
}

echo $html;
?>
