Hi @Destin,
What custom command are you trying to do specifically?
It is likely that whatever code you are putting in the message section is wrong and causing the command to not work.
Always try going through these steps here to first fix the problem: Nightbot Troubleshooting as these fix most problems.
If that does not fix your problem or you need further help with a command reply here and be very specific;
Hopefully, this helps in some way. 
EDIT:
Also when making a topic remember to categorize it correctly so that it can be seen by more people quicker. ( I’ve edited this one to “nightbot” for you )
