Penetration Testing: SQL-Injection escape ')'

[Strcpy <elite_netbios () yahoo com>]

Hi list .

I`m working on a web-application for vulnerability
assesments in order to complete a pen-test job.

there is a vulnerable query there but I can`t escape
it ad use it to go farther .
the page script add a ')' to end of query string
always.
I tried to pass it by useing # or -- or ')'=')' at the
end of my query strings , but non worked :/

here is an example :
i sent this :
A') select name from sysobjects where xtype='U'--


[Microsoft][ODBC Microsoft Access Driver] Syntax
error. in query expression 'city_name='Tehran' and
(agency_english ='A') select name from sysobjects
where xtype='U'--')' 

would you mind please help me ?

[sorry for poor English]

thnq all
