I am doing an exercise from an arcgis tutorial book and everytime I go to use Multiple ring buffer I get this error (see picture)

When I did a regular buffer I did not get any error so I am not sure what the problem is here. Why is it saying that the default1.gdb does not exist and how can I correct this?
