[Serusers] ser+sems configuration problem

hey all , i'm trying to configure ser to act as sip stack for sems i had surf the web to find tutorial talking about that but at end i didn't succeed in doing that however finally i tried to follow that tutorial : http://svn.berlios.de/viewcvs/sems/trunk/doc/Configure-Sems-Ser-HOWTO?rev=4… but with out any success , when i want to redirect the sip message to sems by adding the corresponding lines responsible for that ( from the howto ) and when trying to start ser it said bad config file heres mine : http://pastebin.com/m7872de80 and thats my sems config file : http://pastebin.com/m13c5f7b9 the errors especially appear due to syntax error in this specified line : if ( method=="ACK" || method=="INVITE" || method=="BYE" || method=="CANCEL" ){ thanks in advance
