Use the Control Toolbox from the Toolbars menu...View-Toolbars-Control
Toolbox.
Create your checkbox from this toolbar. Then right click the checkbox and
select Properties. Set the LinkedCell option to the desired cell in your
worksheet. When checked, your linked cell will display "TRUE", otherwise
"FALSE".

I want to add a checkbox into my spreadsheet. What is the best way to do
that?

Once that is done, what should I do to set it up to be referred to in
another area, such as a formula?

Thank you.
