Textarea fields don't work this way. To display the prior value, you
have to do this:
<textarea name="description><?php echo $description; ?></textarea>

The "value" attribute of a select field won't do this for you. You have
to actually set up each option with an either/or choice, like this:
<option value="0" <?php if ($type == 'meeting') echo 'selected="selected"';
?>> - Meeting - </option>
Since doing this is pretty tedious, I use a function here instead:
function set_selected($fieldname, $value)
{
if ($_POST[$fieldname] == $value)
echo 'selected="selected"';
}
And then
<option value="meeting" <?php set_selected('type', 'meeting');
?>>Meeting</option>
