Lua Scripting Resources

Important Update to Custom Scripting

SurveyGizmo's CustomScript Action now supports the LUA programming language.


Legacy Custom Scripting Language Deprecation Plans 

  1. New accounts (created after October 29, 2018) will only have the option to use Lua in scripts.
  2. As of October 29, 2018 Custom Scripting Actions will default to Lua as the scripting type in the Custom Scripting Action for accounts created before this date. You will be able to switch to the Legacy Custom Scripting; though we highly encourage using Lua.
  3. In the long term, Legacy Custom Scripting Actions will be switched to read-only. Read-only scripts will continue to function; you will just be prevented from editing. The exact date on this is to be determined; we will send notifications well ahead of time.


 Go to our Legacy Scripting Documentation.

While SurveyGizmo is one of the most flexible survey tools around, we get requests for customizations that are not available out of the box. This is where JavaScript and Custom Scripting can save the day. If you have scripting chops you can use the JavaScript action or the Custom Scripting action to achieve the survey of your dreams.


[article("bodfy")]

This returns the cumulative sum of all the numeric values answered for the given question ID from complete responses that have been processed.

If summing the values for a question with options (Radio Button, Dropdown, Checkboxes) the function requires numeric reporting values. The function can also sum numeric responses in a Textbox or Textbox List question. In the case of a Textbox List, the responses to all row header will be included in the sum.

The sum that is returned will not include data from any responses that haven't been processed; this includes the current response when the script is run. For instance, if you ask, in a Textbox question, for the number of guests this function can be used to get a total number of guests entered so far by all previous respondents whose complete responses have been processed.
