    Status: Validated

    ISSUE
    When using custom Javascript on a form, the following error appears in a message box: 

    ko is undefined
    ERROR CODE
    RESOLUTION
    1. In the Nintex Forms Designer for the form, navigate to Form Settings.
    2. Under the Advanced tab, select the Custom Javascript includes box and add the following:
      /_layouts/15/NintexForms/ext/knockout/knockout-3.0.0.js
    ADDITIONAL INFORMATION
    The Knockout Javascript library is not automatically referenced by the form. Adding the reference to the library should resolve the issue.
