The Fields that can be used in a Text Block are listed in the right pane of the Text Block Editor. All available Fields are listed. It is also possible that no Fields are available. If the Text Block Editor presents more than one Field Set, you see the available Fields in alphabetical order per Field Set.
A Field can be used to add variable data to a Text Block, such as the name of a customer or the telephone number. Double- clicking a Field, or selecting a Field and choosing Insert the selected field will insert the Field at the cursor position in the Text Block.
