$result = mysql_query($sql);
Because the following line is wrong
//trying to grab it by ranges from the db?
$rows = mysql_num_rows($sql);
should be
$rows = mysql_num_rows($result);
But this is failing...
while ($row = mysql_fetch_array($result)) {
because your
$result = mysql_query($sql);
is probably failing.
Try changing the
$result = mysql_query($sql);
to
$result = mysql_query($sql) or die(mysql_error());
What ever you do, don't use this in production code. But it WILL be
useful with testing.
