The answer is in bold red on the top of your screen. Your site has failed validation - the most likely cause (assuming the url is right) is that there is a page that isn't running the coop or that your site was down when it checked. Did you try to revalidate by clicking the "Validate/Calculate Weight Now"? If you had positive weight, it would be shown in green, not red.
no, I know that the main one isnt validated, but I'm referring to the other sites that have weight yet it totals to 0. I've always had the central account as a random site that doesnt have co-op setup and it used to give me a total weight though.
The others are in red also, so it seems that they aren't validating either. You need to make them validate in order to get them to send weight to the master account. But you also need to make the master account validate or it won't use the weight being transfered to it. You can send 100k in weight to the master account, but if it isn't validating your ads won't be shown.
