Using Hidden Fields for Logic

Whilst not an intended feature of the system, one useful form building technique is the use of hidden fields to condense logic. In doing so, you may find it easier to manage your logical rules and flow when building complex logical expressions that reference many other fields eg, more than 10 rules.

A simple way of achieving this placing the logic you wish to condense and add to on a hidden number field with a default value of one. When you wish to reuse or add to this logic in later fields, you can reference the hidden field (is it = 1) rather than using the complicated logic that the hidden field relies on.
