You're making a method call on an array, which results in a PHP fatal 
error. If your server is set not to log or display error messages, 
it'll just die at that point with no explanation... PHP is so helpful 
this way. :)

Instead you need to run FMSkipRecords() on the FX object before calling 
FMFind(), so it knows which records to fetch.

add here:
if (isset($_REQUEST['skip'] && $_REQUEST['skip'] > 0) {
     $search_result->FMSkipRecords(IntVal($_REQUEST['skip']));
}

(I suggest adding an IntVal() here as a general defensive programming 
practice; input from the web can't be trusted. Consider running 
htmlspecialchars() on output such as the link as well.)

then remove this bit:
