1. If you create a Calculation Retain and then modify the Abacus involved, the Abacus may disappear from the rectangle on the Template. You will then have to drag the Abacus into the rectangle again. It is a good idea to check the Template any time that an Abacus used in a Calculation Retain field is modified.
Note: If you change an Abacus and hear a beep, check the Why? message. The message will provide the name of one Template that is affected. The number of beeps equals the number of affected Templates.
2. You are trying to use the current value of a Field to calculate its own default value. ‘Undefined [Field] becomes [0]’ is a circular calculation in this case, and will not work, although it could be made to work in earlier versions of Helix.
3. You have a default calculation (Calculation Retain) in a Relation that is the target of a post. Defaults are form based, whereas posting delivers values directly into the Fields (bypassing all forms in the target Relation). Therefore, defaults have no effect (and will not be stored) at the target end of posting.
