I can not join data - it must be INNER JOIN

I have two tables, tab_prefixo has number of prefixo and gerente responsible (important data), and in the other one (table tab_valores ), it also displays prefixo , nome , valor and data .

I want, with command prefixo.movefirst , to get the first prefixo from the tab_prefixo table and look for the lines tab_valores in the valor table and copy those data to a new table, the prefixo table, which will contain tab_correio , prefixo , nome , valor and data , and forward mail to that prefix. Then, with gerente command, it passes to the second prefixo.movenext of the prefixo table, and again look for the data that contains the same tab_prefixo in the prefixo table and copy the required data into the tab_valores , and send mail for such a prefix .. and so on.

I'm just able to query with the commands below:

Dim db As Database
Set db = CurrentDb
Dim Linha As Integer

Set prefixo = db.OpenRecordset("select * from Tab_prefixo order by prefixo")
Set valores = db.OpenRecordset("select * from tab_valores")
Set correio = db.OpenRecordset("tab_correio")

prefixo.MoveFirst
Do While Not prefixo.EOF

   If agencias!CODPREF = divida!agencia Then

   correio.AddNew
   correio!prefixo = divida!prefixo
   correio!nome = divida!nome
   correio!valor = divida!valor
   correio!Data = divida!Data
   correio!GERENTE = agencias!GERENTE
   correio.Update

   End If

   agencias.MoveNext
Loop

   'CurrentDb.Execute "DELETE * FROM tab_correio"

End Sub

I actually know that my command is incomplete .. something is missing, and there must be something out of place, but I packed it here.

If someone can help me, thank you very much, because I can not go on .. suddenly I am missing a tab_correio , I am trying everything, but not walking ..
