Assistance for SUB DOMAIN

[Lovelee]

I am an amateur.
I have a site www.aoteatourism.co.nz which I have added a subdomain to, but I cannot figure out how to see it in the content or pages .. I figure then that I have to BUILD it some how.
Can I have directions to do this please??

Sub domain?...

As in you have site.com and also site2.site.com like cmsmsdemo.multiintech.com, see link below \/, or site.com/site2 like multiintech.com/cmsms1.1/ ?...

I have sub domains but it's set up with my host, I go to host control panel and make a new sub domain, like cmsmsdemo, and point it to a CMSMS setup in it's own sub folder or just to get a second level, multiintech.com/cmsms1.1, I just put another subfolder with CMSMS set up in it called cmsms1.1...


mine looks sort of like...

multiintech/
  cmsms1/
  cmsms1.1/
  cmsms2/
  cmsmsdemo/  used as a sub domain
  mit-computers/  actual domain, as in mit-computers.com
  etc....

Each one has it's own CMSMS set up/admin...
