Object names are a unique identifier given to each field in a form template. The object names are also referenced when performing various actions with fields in the form builder. 

The object name is automatically generated for any field added to form in the form builder. This will follow the naming structure "form[field type]_[sequence number]".

To help identify specific fields within your form templates, although not mandatory, it is recommended to update the object name to a unique identifier which relates to the content of that field. For example, where the client's email is populated in a field, the object name could be changed to [clientemail]

This custom naming will also assist in identifying the fields used in other options such as form calculations, lookup fields, multiple choice events, form actions + more. 

Where an object name is already in use, the system will automatically add a sequence number to the end.
