Could you please clarify where the controls are - on UserForm or on Sheet?
If controls are on a sheet then put this sub into ThisWorkbook module
Private Sub Workbook_Open()
' Your code
With Sheets("Sheet1")
.Label1.Visible = False
.ComboBox1.Visible = False
.Label2.Visible = False
.ComboBox2.Visible = False
.Range("B1") = "Month of:"
End With
End Sub
If controls are on a UserForm (Alt-F11 menu Insert - UserForm) then put this code into UserForm's module (Right Click - View Code):
Private Sub UserForm_Initialize() ' The same as Form_Load() in VB
' Your code
Label1.Visible = False
ComboBox1.Visible = False
Label2.Visible = False
ComboBox2.Visible = False
Sheets("Sheet1").Range("B1") = "Month of:"
End Sub
