I think this is what you mean:
strSQL1 = "SELECT tblTempAdult.adLast & ', ' & tblTempAdult.adFirst AS AdultName, tblTempAdult.adBD AS Birthdate, tblTempAdult.adSx AS Sex, tblTempAdult.adCin AS CIN, tblTempAdult.adSS AS [SocialSecurity#], Nz(adPANum) AS [PA#]"
strSQL2 = " FROM tblTempAdult"
strSQL3 = " WHERE tblTempAdult.adCaseName = '" & Me.casName & "';"
strSQL4 = strSQL1 & strSQL2 & strSQL3
lstAdults.RowSource = strSQL4
This gives me headers--i set the row source from vba code.... obviously you have to change field & table names, etc.
Hope this helps..
