Help with error "Cannot find a map remotely named 'blank'

Help with error "Cannot find a map remotely named 'blank'" I'm very new to making maps and I got it working but I wanted to change the music and sky but then it didn't work than after a while I just started over and tried again but I couldn't get it working and I need help because i've been doing this all day. I will go into to a call or whatever

Ahh, sorry, my dumb self didn't notice this was a Ring Racers issue. Unfortunately I'm not familiar with how mapping works in this game, as I'm more used to SRB2.
Sorry again.
