problem with autoExecute - update only

Hi all, Hopefully this is something quick, but I'm a bit stumped. I checked through the archives and didn't come across anything helpful. I can't seem to get the autoExecute function to work when I try to update a record in a MySQL database. I instantiated the object $db['mydb'] in another file, and have included it in my script (in case it's not clear from the code below, this object is being called in line 4). Here's a sample script I made - bare bones for what I'm trying to do: 1. <?php 2. $fields_values = array ('intLocation' => '10'); 3. $table_name = 'sometbl'; 4. $db['mydb']->autoExecute($table_name, $fields_values, DB_AUTOQUERY_UPDATE, 'id=4'); ?> The where parameter (last param) seems to be throwing things off. When it's included, I get the DB_ERROR_NEED_MORE_DATA error of "insufficient data supplied". When I drop the where parameter (id=4), it works fine (though it updates all my records). Throwing the INSERT parameter works fine, too, but I suspect it's because of the lack of the where param. The table structure is two columns - id and intLocation - for the sake of this test. Any thoughts would be appreciated!! Thanks, +gadhra+
