You cannot use count as a function name - count() actually does
something - see the php manual

This is what you may want:

<?php
function my_count($var)
{
if ($var == 10){
$result = $var + 10;
return $result;
}
else {
$result = $var + 20;
return $result;
}
}

$setvar = 10;
echo my_count($setvar);
?>
