I click on halo 2 and 3 service record and it shows nothing is there a way to link it to here?

I went to bungie.net and it was on there

This is more of a general discussion question.

put it in the wrong one my bad

If you have changed your gamertag since you last played, then your stats wil still be linked up to your old tag. To sync them just load up multiplayer or campaign while connected to Xbox Live and play a few games, eveything should sync up shortly afterwards. Halo 2 stats won’t sync though as the original Xbox Live servers are no longer online. If you want them to show, you’d need to switch back to using ghr gamertag you had when playing Halo 2 online
