    Post Newbie VB Help much appreciated

    I am preforming a data integrity check by using a select count. i noticed that the developer was only passing 1 expression if Val(sRows) >1 but he forgot to check for zero record. I tried to change the code in the two variations below and syntax checks correctly but I do not get my error message. Can anyone assist me. please



    'Step 2 - Data Integrity Check
    sSql = "select count(*) from F5542EP where NRLOTN = '" & Rsp & "' " & _
    " and NRYN01 = 'Y' and NRNREEPROM <> ''"
    DB.Execute(sSql, sCols, sRows)

    If Val(sRows) > 1 Then ' if val(srows) = 0 then
    App.CallForm("FADERROR" & " -SNR=ESNR1", True)
    Exit Sub
    End If

    Variations
    If Val(sRows) > 1 Or Val(sRows) = 0 Then ' if val(srows) = 0 then
    App.CallForm("FADERROR" & " -SNR=ESNR1", True)
    Exit Sub
    End If

    If Val(sRows) <> 1 Then ' if val(srows) = 0 then
    App.CallForm("FADERROR" & " -SNR=ESNR1", True)
    Exit Sub
    End If
