hey i am trying to customise a form with the advanced html template, is there a function to spit out all the data, i have tried looking through freemarker examples but can't get it to work

Could you clarify 'spit out all the data'?

Ideally i am looking at changing the price export, I am can't find reference to all the fields so I want to just use the template to show every field I could use

SA# 73900 provides all of the fields available for each of the record types. Otherwise in the WYSIWYG editor you can also 'add' a field and see what is available that way.
