Problem updating/deleting DB entries (recordset not seeing connections)

Question

I recently had to make changes to my database and now for some reason, the update/delete page no longer sees any entries from my database. Which makes no sense to me.
The page in question is http://209.62.4.98/~parishpr/admin/properties.php
and the PHP Code is on: http://209.62.4.98/~parishpr/properties.txt

Answer 1

OK, I'm starting to figure things out but not completely. I still need some help. Here's what I've figured out so far.
If you go back to the original SQL code you'll see this:
SELECT prop_id, category, property
FROM properties
WHERE prop_id = 123456789
ORDER BY property ASC
That brings up no data at all. Eliminate the WHERE statement completely and all records appear but in all categories. Still not good.
Here's where things get interesting. Try this:
WHERE prop_id = 21
Ah! Now I get the record for prop_id #21. And only prop_id #21. But again, it's listed in all four categories. But it does answer why using 123456789 doesn't work.
So what's the solution?
