In Infigo Designer, there are some settings which are disabled by default due to the fact that they are considered complex and can potentially cause issues with your templates. An example of this would be the Javascript Management item in the Infigo Designer dropdown menu, which allows you to use our Javascript Wizard to create your own scripts.
To enable this, you simply need to navigate to Infigo Designer -> Configuration and enable 'Advanced Version'.
Once enabled, simply click 'OK', save your current PDF, and close Acrobat.
Note: you will need to ensure that Acrobat is completely closed in order to ensure that the configuration is re-loaded and the appropriate features are enabled. The best way to ensure this is to restart your computer, however this may not be required.
