In Memberships, when editing the tax deductible amount to a membership level on the Benefits tab you may receive the error: A level's tax deductible amount cannot be greater than its lowest-valued term option.
This error indicates the tax deductible amount you specified on the Benefits tab is greater than the price listed for that membership level. Altru will not allow the tax deductible amount to be greater than the price of the membership level.
To fix the error:
Increase the price of the membership on the Levels tab.
Decrease the tax deductible amount on the Benefits tab.
