Userform - Continue and cancel command buttons code

Hi all,

I hope someone can help me please?

I have my userform and currently it goes through my excel document and ticks a check box if the header is there (fantastic!).
I am hoping to add two command buttons to the end to allow the user to continue with the macro or cancel the macro and return to the workbook but I am struggling with the code I need for this - could someone please advise me on this?

Below is the code for the check boxes which I will need to add to for my other two buttons.

Thanks for your help.

Private Sub UserForm_Initialize()

  c01 = "|" & LCase(Join(Application.Transpose(Application.Transpose(Rows(1).SpecialCells(2))), "|")) & "|"
  For j = 1 To 10
    Me("Checkbox" & j) = InStr(c01, "|" & LCase(Me("Checkbox" & j).Caption) & "|") > 0
  Next
End Sub
