Forms :: Continuous Form With Command Button On Each Record To Open Another Form

I have a continuous form in which I put a command button for each record called "detail". I would like to click on the "detail" button and make it open another form containing all (and only) the info on this record.

At first I refused to use an "id" to link both forms, but finally I added the "id" in the table... however still does not work.

continuous form: "04 - GASTOS_BUSQUEDA"
id field on continuous form: "Gastid"

pop-up (details) form: "GASTOS_EDITAR"
id on pop-up (details) form: "editar_id"

This is what I have tried on the "click" properties of the "details" button field (called "btn_editgs"):

1)
DoCmd.OpenForm "GASTOS_EDITAR", acNormal, , "[editar_id] = " & Me.Gastid

2)
DoCmd.OpenForm "GASTOS_EDITAR", , , "[editar_id]=" & Me.Gastid

3)
stLinkCriteria = "[editar_id]=" & Me![Gastid]
DoCmd.OpenForm "GASTOS_EDITAR", , , stLinkCriteria

4)
Private Sub btn_editgs_Click()
On Error GoTo btn_editgs_Click_Err
Dim strWhere As String
strWhere = "[editar_id] = " & Me.Gastid
DoCmd.OpenForm "GASTOS_EDITAR", , , strWhere
btn_editgs_Click_Exit:
Exit Sub
btn_editgs_Click_Err:
MsgBox Error$
Resume btn_editgs_Click_Exit
End Sub
