[brindlogcool]

Edit script has options like Web files option and the Field data . what is the difference between two. Both are having the same options.

Web File: Load a file coming from a website

Field data: Load specific rows coming from a field located in a database

Field data is not a popular way to load specific rows from a field it's a quirky syntax  - most run a loop over the field like:

LOAD max(FieldValue('Id', recno())) AUTOGENERATE FieldValueCount('Id');
