SAVE MY KEYBOARD- MySQL resources is invalid.

Question

I have two pages that both use the same include. I posted
awhile back b/c
one of them would not work. I came in, redid the page -
VOILA! It worked.
Now it doesn't. Somebody, please save my machine from a
pounding!!!!!!
Working page:
http://demo.mediachurch.com/news.php
Look at the News Highlights. This section is the section
that, until this
morning, was working OK on my main site.
Nonworking page:
http://demo.mediachurch.com
This page has the following error on it. It looks like for
some reason the
SQL is not being read properly - but how could that be if
it's being read on
one page OK?
Warning: mysql_num_rows(): supplied argument is not a valid
MySQL result
resource in /home/mdemo/public_html/app/nl_FrontPage.php on
line 21
SQL:
THis is lines 1-23 on the nl_FrontPage.php file:
$maxRows_rsFrontPage = $mcArticle;
$pageNum_rsFrontPage = $mcPage;
if (isset($_GET['pageNum_rsFrontPage'])) {
$pageNum_rsFrontPage = $_GET['pageNum_rsFrontPage'];
$startRow_rsFrontPage = $pageNum_rsFrontPage *
$maxRows_rsFrontPage;
mysql_select_db($database_mcDemo, $mcDemo);
$query_rsFrontPage = "SELECT * FROM tblnews WHERE
newsPublish = '2' ORDER
BY newsOrder ASC";
$query_limit_rsFrontPage = sprintf("%s LIMIT %d, %d",
$query_rsFrontPage,
$startRow_rsFrontPage, $maxRows_rsFrontPage);
$rsFrontPage = mysql_query($query_limit_rsFrontPage,
$mcDemo) or
die(mysql_error());
$row_rsFrontPage = mysql_fetch_assoc($rsFrontPage);
if (isset($_GET['totalRows_rsFrontPage'])) {
$totalRows_rsFrontPage = $_GET['totalRows_rsFrontPage'];
} else {
$all_rsFrontPage = mysql_query($query_rsFrontPage);
$totalRows_rsFrontPage = mysql_num_rows($all_rsFrontPage);
$totalPages_rsFrontPage =
ceil($totalRows_rsFrontPage/$maxRows_rsFrontPage)-1;
In the index file, it's linked like this:
$mcArticle = 4;
$mcPage =2;
$fpStyle = 0;
require("app/nl_FrontPage.php")
In the news files it's a bit more complicated, as this page
is only
displayed after a few conditions are [not] met. However,
nested in the if
statemenst is this:
$mcArticle = 4;
$mcPage =2;
$fpStyle = 1;
require("app/nl_FrontPage.php")
Does anybody have any general clues as to what I'm looking
for? This is
absolutely driving me nuts.
TIA,

Answer 1

Thanks for responding, Joe
The query comes out fine (see here:
http://demo.mediachurch.com/index2.php
and when I run the SQL on the server, it give me exactly what
I want.
What's just *amazing* to me is that the other file it's
included on should
be the one that has problems.
news.php
includes display.php
(if)includes nl_News.php
(if)includes nl_FrontPage.php
The index page has this:
index.php
includes nl_frontPage.php
*sigh*. I"m going to takea break, i'll check back tomorrow
when it's too
hot outside to work (or when i just get Lazy)
