IE does not see external css file

[unpresedented]

Hi.
I wrote something like:

echo "test <br>";
?>
<link rel="stylesheet" type="text/css" href="mystyle.css" />
?>
echo "<table class="my_table">;
echo "<tr><td>this is a test</td></tr>";
echo "</table>";

firefox can see the style and apply it to the table but IE 8 not seeing it !! this is really a weird behaviour !! can anybody help me with this ?
thanks in advance ...

p.s. i also tried to include the property : media=screen .. but negative :(

i found out the reason.
it's because that there is an error in the css file which causes IE 8 to ignore the whole file.
