When you are looking at your list of activities or reports in the Configurator, you may notice a red exclamation point next to the name of the report/activity.
This means that you have the report or activity configured to be a "File" template type. This can include the following template types: "File - Use Field Codes" and "File - No Field Codes". However, there is not a file associated with the report or activity!
To correct this, you can either upload a Word doc (using the paper clip icon) or you can change the template type to either "None", "Text and User Attached File", or "File - User Will Attach".
