Why are you opening new PHP tags when you are already in some? <? $us = **<?** ... It's just not necessary. Check if ud is set, otherwise it is 0.

$us = isset($_GET['ud']) ? $_GET['ud'] : 0 ;

$echo is just wrong; echo is not a variable but a language construct. Read the documentation[^] to learn more. And again with the opening of more PHP tags.

echo '$ud = ' . $us;

If at first you don't succeed, you're not Chuck Norris.

Please engage your brain. <? echo $ud ?> instead of <? echo $_GET['ud'] ?>
