Markers are in the form #FIELD# and %var% where FIELD is the name of a field and var the name of a form variable.

Any JSON supplied to the template will be escaped.

Repeating Pages

The following tokens can also be used:

  • #PAGEINSTANCE# - The page instance that's currently being displayed (zero-based, ie the first instance is 0)
  • #PAGEINSTANCEDISPLAY# - The user friendly current page instance (one-based, ie the first instance is 1)
  • #PAGEINSTANCEMIN# - The minimum number of instances set in the forms designer
  • #PAGEINSTANCEMAX# - The maximum number of instances set in the forms designer
  • #PAGEINSTANCECOUNT# - The current number of instances (of this page) that have been generated
