[Exim] Router problems

Folks,

I'm currently trying to figure out a way of determining wheither a email should be sent to the local mail server or a remote one based on information stored in a LDAP directory.

the theory is that email will come in for users at a specific domain, eg fish.co.uk. exim will then query the M$ AD server to check the users physicaldeliveryofficename object. If the office is the local one then send to the local email server. Else process via the lookuphost router.

At the moment I have hit on a syntax error and can't spot it. The error is:
Sep 17 15:29:41 colorado exim[15184]: [ID 631539 mail.alert] [1\2] 2002-09-17 15:29:41 Exim configuration error
Sep 17 15:29:41 colorado exim[15184]: [ID 631539 mail.alert] [2/2] missing quote at end of string value for condition in line 336


the router is:

fish_co_uk:
   condition = "${if
    and {
            {match
                {$domain}
                {fish.co.uk}
                {$domain}
            }
            {eq
                {Leeds}
                {${lookup
                    ldap {
                        user=\"CN=ldap readonly\"
                        pass=\"nottelling\"
                        ldap://server/ou=Users,dc=leeds,dc=intnernal
            ?physicalDeliveryOfficeName?(cn=${sg
                                {${lc:$local_part}}
                                {^([a-z]*)\.([a-z]*)\$}
                                {\$1 \$2}
                            }
                            )
                        }
                    }
                }
            }
    }
}"
   driver = domainlist
   route_list = "* internalmail.local byname"
   transport = remote_smtp
