I think you have HTML and PHP mixed up. You cannot use the an ID more
than once in an HTML page, class yes. For variables, you do say:

<?php

if(isset($_GET['year']))
{$year = $_GET['year'];
//do some testing to make sure the value is what you want}
else
{$year = 1960;}

echo "<p>The initial year is ".$year.".</p>";

echo "<p>Loop 10 years:</p>";

for($i=0;$i<10;++$i)
{
echo "<p>The year is now ".$year+$i.".</p>";
}
?>

$_GET(variable) does not work. You need $_GET[variable].

Did you ever think about using the source, PHP.net?
