How do I get the base URL in the formula editor?
I'm building a custom button that when clicked creates a task. In the task comments, I'm building a URL to direct the assignee to the Account Team add page. I need to know the instance I'm on in order to build the button properly.
Is there a way to get the base url (https://na6.salesforce.com) or instance (na6) in the formula builder so I can avoid hardcoding an instance?
