<input type="button" name="Next" id="Next" value="Next" onclick="showNextQuest(<?php echo $_POST  ['$qtnid']; ?>)" />

should be

<input type="button" name="Next" id="Next" value="Next" onclick="showNextQuest('<?php echo $_POST  ['$qtnid']; ?>')" />

To make it a string, not a varname

If the values are strings you should also put single quotes around your PHP if you want to pass the value as a string:

showNextQuest('<?php echo $_POST['$qtnid']; ?>')
