on my server in library manger i made one called chrismedia for location is this where i put the noip address?
No, that's not the place on the server side.
On your end, in MC under the tree, get into Services & Plugins > Library Server.
Click the options button.
Select Manual Port Selection and fill in the desired port
(I really wouldn't use 80, I suggest using a port near 10000, then you'll have to set your firewall to allow it in).
Then click the Start Server button.
You'll see some status text indicating that it's waiting for connections.
On the remote end, get into File > Library > Library Manager.
Click Add button.
Fill in your host:port there.
ex. xtacbyme.noip.com:10000
Click OK.
Will get connected and download the library unless you have some firewall issues.
