when i try i get this message, my server is hosted with Xenon Servers and i have the "craftbukkit" plugin installed propper so i dont know?

One of the following suggestions may help you:
* Your server is currently offline.
GameTracker needs your server to be online before you can add it to our database. Please restart your server and make sure it's up before hitting ADD SERVER again.
* You entered the wrong query port.
Please update your query port and hit scan again
* Your server is firewalled.
Please turn off any firewall you have that may block scanning
* Your server isn't configured to respond to scan requests.
In order for GameTracker.com to successfully scan your Minecraft server you will need to install either the CraftBukkit or Canary plugin.
CraftBukkit Instructions [Offical Site]
1. Install CraftBukkit
2. Get the CraftBukkit Plugin
3. Put the CraftBukkit Plugin in you servers "plugins" directory
4. Edit "server.properties" and set the "server-name"
5. Restart your server or reload the plugins with "/reload"
Canary Instructions [Offical Site]
1. Install Canary
2. Get the Canary Plugin
3. Put the Canary Plugin in you servers "plugins" directory
4. Edit "server.properties" and set the "server-name"
5. Add "MinecraftViewer" to your plugins in "server.properties"
i.e &quotplugins=MinecraftViewer,CuboidPlugin"
6. Restart your server

I would recommend checking this one. It would not have to be turned off if you can open the appropriate ports. Contact your provider for support on this if you do not have access to it.

Please make sure your firewall is open and follow the directions here to add the plugin and enable querying on your server:

what port would need to be opened, what port is the scan using?

This would be the port you are entering on the add server form.
