Tips: -make sure your clan tag appears as the last one known by Bungie.net. You can find this under the sneakernet part of the "avatar and theme" tab. -be patient when inputting the code. It's very long and you really have to pay attention. -make sure your brightness is just enough to see the numbers. The higher the brightness, the harder it is to actually see the numbers (or at least it was for me). Also, is this the account linked to your xbox live account? If not, there is no way to link any of your HAlo stats. The account had to have had Halo game history on it before Bungie passed Halo to 343i. If you have multiple accounts, try finding the one with your stats and linking it to your main account.
