Hi Amanda,
It looks like your looking for empty parent_project_id's which would mean
there is no parent_project_id in the results of the first query.
$query ="SELECT * FROM projects WHERE parent_project_id is NULL OR
parent_project_id = ''";
> The above should be:

I think it should be
$id = $projects[$key]['project_id'];
Since parent_project_id would be empty.
Matthew, thanks for your help on my post. I'm using adodb so I had to remove
the force (boolean) parameter. I'm new to adodb and your sample code was
very helpful and educational. It seems to be a lot more powerful then phplib
which I'm moving away from.

Yeah, welcome/Object.tpl seems to be causing a problem.
