Hello All, trying to make sense of this formula that I am trying to achieve

If(Not(${Properties.Tax Credit Received Following Year},(Adddate(${Properties.Exit Date},5475,'DAY'), Adddate(${Properties.Exit Date},5110,'DAY')

I have a check box "Properties.Tax Credit Received Following Year" and an Exit Date Value

When checkbox is checked - I would like to add 15 years to the exit date

When checkbox is unchecked - I would like to add 14 years to the exit date

Thank you in advance.
