The GetSectionMD5 statement requires a message section number and variable name, in the format

GetSectionMD5 <message section number> <variable name>

The following example will get the contents of the first section of the message, perform an MD5 hash on it, and put the result into the ${myMD5Hash} variable

GetSectionMD5 1 myMD5Hash

  ${SectionId} = ${1}
  GetSectionMD5 ${SectionId} myMD5Hash
 EndIf
