Thanks,

I changed the query to read like this:

$query = "UPDATE about SET category_id = $category_id_new WHERE
about_id = {$_SESSION['about_id']}";

All on one single line.

But no dice- no update occurs! I've echoed out the query itself, and
the variables are showing up as they should:

UPDATE about SET category_id = 31 WHERE about_id = 5

I wrote this function to execute 2 more functions IF this query
evaluates true. Both these functions are executing, but the
category_id field is not updating.

I dont mind rewriting my code, but I wish I could understand why when
it doesn't work as expected.

Thanks to all of you for trying to help.
