Never tried UserForm checkboxes before so I don't even know how to point to the Checkboxes in a Userform.

This is what I have at the moment....and I know, I know, it is completely wrong. Please help?

```
Private Sub Step1_Confirm_Click()
    Dim i As Byte
    Dim Done As Boolean

    For i = 1 To 4
        If Step1_(i).value = True Then
            Done = True
        End If
    Next i

    If Not Done = True Then
        MsgBox "Please make sure you have done all"
    End If

End Sub

```

Basically I have:

1. A Userform called `IOSP_Acc_R_Approval_Step1`
2. 4 checkboxes called `Step1_1`; `Step1_2`; `Step1_3`; `Step1_4`
3. A button called `Step1_Confirm`
4. I want the button to show Error, if not all checkboxes are checked - meaning that all checkboxes have to be checked....(in case my English is too bad to convey my meaning)
