I have a total of 4 fields where 3 of them must equal the 4th value. So...
$amount of 'Write-off' + $amount of 'Goodwill' + $amount of 'Customer' must equal what is shown in 'Exposure'
The rule should fire if the first 3 fields are not equal to the amount shown in the 'Exposure' field.
Any help in writing this formula is appreciated.
