cracking password with part of it knowm

I need to crack a series of hashed passwords and for some reason, it's exhausted without cracking the password. The passwords are given to me in the form of NCL-HQNT-XXXX, with the last 4 being numerical digits. I've been doing a lot of reading up on this and it should be straight forward.

My command is:

hashcat -m 0 -a 3 crackthese NCL-HQNT-?d?d?d?d --force

The hashed passwords are in the "crackthese" file (5 of them). Also, this is for NCL, but not the competition. I'm still working in gymnasium. Just FYI, so you know I'm not trying to cheat on this. I'm still trying to learn it.

Any idea what I'm doing wrong?

Thanks
