Killing all messages

I wrote the following code and it tested fine in the testing tool. When applied to the route, it kills all messages. I only want vitals with nursing station {CI} to pass.

Is my return wrong?

********* CODE BELOW ***********************

set filter_name “MedStation_filter”

           set fld_sep [csubstr $msg 3 1]  ;# hl7 Field Separator

#echo $fld_sep

           set cmp_sep [csubstr $msg 4 1]  ;# hl7 Component Separator

#echo $cmp_sep

           set rep_sep [csubstr $msg 5 1]  ;# hl7 Repetition Separator

#echo $rep_sep

           set slist [split $msg n]       ;# Get segments

echo [csubstr $slist 1 3]

           set seg “”                      ;# Just in case

#

           foreach seg $slist {

echo “SEGNAME: [csubstr $seg 0 3]”

               if [cequal [csubstr $seg 0 3] PV1] {

                   set fields [split $seg $fld_sep]

                   set room_bed [lindex [split [lindex $fields 3] $cmp_sep] 2]

         set station [string range $room_bed 0 1]

echo “Room and Bed: $room_bed”

echo “Station: [string range $room_bed 0 1]”

                   if [lcontain {CI} $station] {

                     echo “$filter_name – passed – station in {CI}”

                     return “{CONTINUE $mh}”

                   }

                   break

               }

           }

#

           echo “$filter_name – failed all test.”

           return “{KILL $mh}”

       }

   }

}
