Lab 3b

I need help in creating the "New Resource" when trying to complete step 60. When I Click on "+New Resource", I get the popup box shown in the second image. When I click cancel, done, or the X for that popup window, it gives me the error message shown in image 3. When I try to follow the popup box's instructions on saving the flow and refreshing the page, I then get the pop up box with the message show in the fourth image. I would appreciate your help as I have tried going through steps 35-55 several times now with no change. Thanks in advance.
