You will get this error if you do not have a sheet with a name that
matches
the variable zone. Also you do not need the loop. Try it like this:

Private Sub Cmd_Valid_Click()
Dim sht As Worksheet
Dim LaPremiereDispo As Long
Dim zone As String
If Range("R28").Value = 1 And Range("R28").Value <= 12 Then
zone = "Feuil" & Range("R28").Value + 4
MsgBox "Selected sheet is " & zone
On Error Resume Next
Set sht = Sheets(zone)
On Error GoTo 0
If sht Is Nothing Then
MsgBox "Sheet does not exist"
Else
LaPremiereDispo = sht.Range("E65536").End(xlUp).Offset(1, 0).Row
MsgBox "the first cell for this month is " & LaPremiereDispo
End If
End If
End Sub

Hope this helps
Rowan
