A family of Microsoft word processing software products for creating web, email, and print documents.
Form checkboxes can appear on sheets or userforms, but either can be linked to a cell (if the cell value is TRUE the checkbox is checked, and visa versa; if the cell value is FALSE the checkbox is unchecked and visa versa).
Rightclick the checkbox, format control, control tab, add a cell link. The linked cell will be overwritten with either TRUE or FALSE depending on the checkbox state.
Then replace that TRUE or FALSE in the linked cell with a formula to check if the user entry cell matches your target value. In this example, I linked the checkbox to D2. If desired, hide that helper column so your users don't see the TRUE/FALSE values
