Migrating Users To New Server

Hope somebody can help a novice, so I can impress my boss.

I've got to move a database to a new server and I'm trying to use Gregory A Larsen's sp_help_revlogin script http://www.databasejournal.com/features/mssql/article.php/2228611.

It works perfectly for all users, but I want to limit it to one database by using his suggestion shown on that page:

SELECT sid, name, xstatus, password FROM master..sysxlogins
Your_db..sysusers b on a.sid = b.sid
WHERE srvid IS NULL AND name <> 'sa'

However, when I make the changes, so it looks like this:

SELECT sid, name, xstatus, password FROM master..sysxlogins a join
int_test..sysusers b on a.sid = b.sid
WHERE srvid IS NULL AND name <> 'sa'

I get this error when I try to run it:

Server: Msg 209, Level 16, State 1, Procedure sp_help_revlogin, Line 12
Ambiguous column name 'sid'.
Server: Msg 209, Level 16, State 1, Procedure sp_help_revlogin, Line 12
Ambiguous column name 'name'.
Server: Msg 209, Level 16, State 1, Procedure sp_help_revlogin, Line 12
Ambiguous column name 'password'.
Server: Msg 209, Level 16, State 1, Procedure sp_help_revlogin, Line 12
Ambiguous column name 'name'.

Can anyone see what I'm doing wrong.

The database that I want to limit the script/procedure to is called int_test on the same server, and I've checked that the table sysusers does exist, and that it has a column called name.

Any help would be greatly appreciated.
