Changes

A way to update a field based upon an expression that is run on page load. This applies only to the [[Custom Field Type: Special – Calculated Value|Special - Calculated Value]] custom field type. This setting is configured using [[:Category:JavaScript|JavaScript]] syntax and works by populating the input field on the form with the specified expression every time the form is loaded. This requires the user to save the form to actually save the field value.

===Advantages:===

*Visibility (i.e. users can see the field and verify the default value before it is actually saved and stored into the field)

==[[Value Stores To]]==

A way to duplicate a field value and store it into another field. This is configured through the custom field settings page. This setting works by duplicating a field value into another field any time the first field is saved. This requires the user to save a value into the first field.
