If Formula

I need a formula that if a checkbox is checked, it populates the data of another cell.

Example, I am tracking the # of approved delays in days.

I need the formula that when the [Approved Bonus Delay] is checked the [# of Days Delay] is copied into the [#of Approved Bonus Delays] cell

The formula I currently use is populating a 1 and not 55 (or 555)

=IF([Approved Bonus Delay]5, 1, [# of Days Delay]5)
