If we don't know the amount of a planned gift we add it as $0 and do not add it to revenue. When the payments are received, we add an addition for the amount of the gift. In order to add the addition to revenue so we can apply the payment, we have to change the planned gift to having an amount (i.e. $0.01) in order to add the addition to revenue. We then have to go back to the planned gift and change the original gift amount back to $0.  If an amount is added in the area of additions, the ability to add to revenue should be opened. We shouldn't need to be required to add an amount on the original planned gift.
