Identifiers are used as an internal way of referring to a question in the site. They are most commonly added to questions when you require the use of Advanced Expression Piping (AEP) within your form. They are short, one word, values made up of letters and numbers.
In order to add an Identifier to a question:
Question identifiers are case sensitive, must begin with a letter, and may only contain letters, numbers, and underscores.
TIP! To ensure that you can easily identify the question later, make sure the identifier is related to the question. For example, if you have a question that asks for the "Home Address" of your applicant, an identifier you may use would be home_address or home address. For longer questions, it is still important to keep the identifier short, therefore for questions such as "Name your top 3 favourite colours" your identifier may be favourite colours or three colours.
When the identifier is added to the question this is how it will be identified internally throughout the site, it will replace the original question which is why it is important that it is related to the question so you can easily identify it later. It will be displayed in the following sections:
The identifier will not be displayed to any of your end-users when they are filling out their forms
