I have been trying to get the Concatenate Function from Duane to work. I'm not clear on the ID fields used as an example in the comments of the code because the foreign key and the primary key share the same name. I'm assuming the reference to "FamID" is the same ID in all three places. (The foreign key in FamMem???)
example
'tblFamily with FamID as numeric primary key
'tblFamMem with FamID, FirstName, DOB,...
'return a comma separated list of FirstNames
'for a FamID
' John, Mary, Susan
'in a Query
'SELECT FamID,
'Concatenate("SELECT FirstName FROM tblFamMem
' WHERE FamID = " & [FamID]) as FirstNames
'FROM tblFamily
example
'tblFamily with FamID as numeric primary key
'tblFamMem with FamID, FirstName, DOB,...
