Parameters

formElements: Contains form element data (Key: property "Field Name" if set, otherwise a unique id. Value: the input from the user). Key must be unique. Duplicate keys will lead to the value being overwritten. It is therefore recommended to set the "Field Name" property as a formula with a unique result.
duplicateKeys: Duplicate keys, which lead to the original value being overwritten in formElements, will be listed inside this object.
