How to determine missing permissions ?

I've been tediously working on setting up scripts to limit access through
our different departments accordingly. I've been working at creating the
tightest set of perms first but can't seem to get it working. I've posted
the script obviously but figured I'd ask if there were some way to determine
what permissions are required when I get an access denied error...
In the script it is assumed that there are already 3 logins created and
added to the current database. I know there is alot to go on the script as
far as error checking, previous existence etc....but in a controlled
environment (my localhost at this time) this should work. The problem is
after running this I couldn't even open and view db properties...I had to
drop and recreate the user from login. Then I still couldn't select data
from any table.
THANKS!!!! For any input. I know I'm missing it somewhere here bigtime.

I have a couple questions,
Does the login have sys_admin privileges?
does the user have db_owner fixed database role privileges?
Have you issued GRANT ON SELECT.... for more details please refer to the

Do you mean for the user running the script? If so I'm running the script
as 'sa'. If you mean the user 'web' then absolutely not. We want to
restrict them to selecting/updating data. As shown in the script below they
are explicitly granted select on all tables/views...

I have. That is how I got this far...but I'm having trouble now finding
what is missing. I don't want the user 'web' to have sys_admin privileges.
But with the script below the user 'web' now gets 'Invalid object name
'tblname'' when trying to select data from a table.

Pobably because the "web" user/login is not the owner of the "tblname", Can
you check it?
