-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I tried to call is_user_in funktion with a variable as group name. I want to create the group name on the fly, when a INVITE arrives. if(is_user_in("To", $var(a))) { ... } I got this error message: 0(27274) xl_parse_svname: parsing [$var(a)] 0(27274) xl_lookup_spec_name: found [fu] [18] 0(27274) find_cmd_export_t: found <xlog>(2) in module xlog [/home/hk/openser//lib/openser/modules/] 0(27274) parse error (479,27-34): syntax error 0(27274) parse error (479,34-35): bad arguments Is there a way to do dynamic group names für is_user_id? regards helmut
