Starting on 8/15/21, all Formula URL and Formula Rich Text fields no longer accept new JavaScript changes.
If you try to add or edit an existing field that contains JavaScript, you receive the following error message:
As we've recommended in the past, if you don't have a reason to change the field properties of the extension execution buttons we created for you, take no action and continue to use them as you always have.
If you do feel you need to alter the buttons yourself, please review our JavaScript changes webinar content, which includes detailed instructions on how to remove JavaScript and still execute our extensions in the methods you always have.
If you have any questions or need assistance with this task, please submit a technical support case.
