Sometimes we send users a special link that takes them directly to the online recorder and sets the Inventory name. For example, a link to do the test inventory might have ?inv=test as the last part of the URL. When we do that, it locks the inventory name and it cannot be changed. We have seen cases where a browser might auto-complete the URL and include the ?inv=test part even though you no longer want to do another test inventory. The easiest way to fix this is to log in to the main page (https://modeltalker.org) and then use the Recording > Online Recorder menu to get to the recorder. If your browser still insists on adding ?inv=test to the address, you may be able to delete that from the address bar.
Why is the system making me redo the test inventory even though you said I can start the standard inventory?
