Using this code, the innerHTML isn't changing. How do I make the innerHTML change? Maybe use setTimeout?

Code:

<?php
if(isset($_COOKIE['pollchoice']))
echo "<script type='text/javascript' language='javascript'>document.getElementById('pollarea').innerHTML=\"poll results here\"</script>";
?>

Any ideas? I'm sure this is much easier than I'm making it :P

The javascript looks syntactically correct.
try this quick test:

<?php print($_COOKIE['pollchoice']); ?>

Why do you write javascript code from php?
You should either test the cookie in js, or write #pollarea's content directly in php. There is no use for js here.

Since you're testing the cookie in php, why are echoing javascript that write html ?

It would be simpler to write directly:

<div id="pollchoice"><?php
if (isset($_COOKIE['pollchoice'])) echo "poll results here";
?></div>

or, if you don't need the empty div:

<?php
if (isset($_COOKIE['pollchoice'])) echo "<div id=\"pollchoice\">poll results here</div>";
?>
