pop up form within userform to confirm choice

[jpruffle]

Hi,

I have a button within a userform that clears the form:

Private Sub CommandButton2_Click()
'Pop up to double check
     ClearCheck.Show
'Clear Page One
    Me.Actnumber1.Value = ""
    Me.How1.Value = ""
    Me.Whoact11.Value = ""
    Me.Whoact12.Value = ""
    Me.Whoact13.Value = ""
    Me.Act1Date.Value = ""
    Me.Comp11.Value = ""
    Me.Result11.Value = ""
    
End Sub

What I want is when it is clicked the userform ClearCheck is shown that basically asks - Are you sure you wish to continue Yes/No.

If Yes I want the rest of the above Sub to continue. If No then Stop.

Can you advise. The ClearCheck code is below:

Private Sub CommandButton1_Click()
Unload Me
End Sub

Private Sub CommandButton2_Click()

End Sub

Thank you in advance.
