Hey,
Sorry for the late reply.
Had a chance to look at the log and I see on step 8 of 9: you have Default Values assigned for the AssignedTo fields.
The default values were set to Nicole, it could not find that because Nicole on the system is is titled: 'Nicole Hull'. As per her User Name under Customize > Users.
Head over to step 8 edit the AssignedTo fields and from the dropdown choose Nicole Hull.
Then repaste the HTML code onto your domain and try again.
