what does That is the hostname which is reserved mean?

[Webdetailing]

When I got to make a reseller I get a message that it can not be done and saids this below "That is the hostname which is reserved. Either change the hostname, or use a different domain"

What do I need to to do to be able to use the domain I type in?

Sounds like you are trying to create the domain that is currently being used as your systems hostname... log into ssh and run the command "hostname", is that the domain you are tying to add?
