Proposal: Calculation element for Form Builder
We would like to have a new element that allows basic arithmetic operations with number fields. The idea is to be able to sum up several number fields or compute an average. The implementation might make use of the field references suggested in issue #4576.
It should also be possible to include constants in the computation.
Trying to set up a scoring form for e.g. an event – it would be great to be able to compute the average score and store it in CiviCRM.
No such behaviour currently exists.
A computed form element is available that can use input fields as well as fixed values.
