I am a bit confused on what you are doing here, but you have a number
of problems with how you are evaluating your arrays.

First, surround your array vars with curly brakets in the SQL
statement. The common syntax would be:
{$_POST['lastName'][$n]}

Also, you want to count the number of elements of the arrays by a
count of the names:
for ($n=0;$n<count($_POST['firstName']),$n++)...

To see what is being posted for debugging, use print_r() function:

echo "<pre>";
print_r($_POST);
echo "</pre>";

Hope this helps.
