The comparison between two nodesets is a little bit different than the comparison between a
nodeset and a number, so i suggest to try like: 
recordset[@rsName='Codes']/record[field[@fieldname='Section']='2'][field[@fieldname='ID']
 = number(recordset[@rsName='Memberships']/record[1]/field[@fieldname='RefEntryActivityID'])]
