One checkbox that selects multiple checkboxes

I am creating a checklist spread sheet. I do not have any experience with VB, so I am unsure as to what code to write to do this: I created many check boxes, but I want to designate one check box that can select multiple check boxes when clicked and deselect check boxes when clicked again (unclick). I have seen other codes for this, but I have no clue as to conform other written codes to my worksheet. An easy step by step guide would be great instead of a copy and paste this code please.

I do not remember asking for help on creating a worksheet. I have it created, my issue was writing code for having one check box selecting multiple check boxes. That sounds like a certain problem to me. Not a do it for me cause I am incompetent question. But thanks for the help .

If CheckBox1.Value = True Then

CheckBox2.Value = True
CheckBox3.Value = True
CheckBox4.Value = True

endif
