Bonjour,
Une possibilité :
Private Sub CommandButton1_Click()
i = Cells(Rows.Count, 1).End(xlUp).Row
For ii = 1 To 10
Cells(i + ii, 1) = "Groupe " & ii
Cells(i + ii, 2) = CLng(TextBox11)
Cells(i + ii, 3) = Format(Me.Controls("TextBox" & ii), "###0.00")
Cells(i + ii, 4) = Format(Cells(i + ii, 3) / 12, "###0.00")
Cells(i + ii, 4).NumberFormat = "0.00"
Next
Unload Me
End Sub
A+
