Why isn't this printing out values?

Why is this printing out one value for each table and how do I fix it?

It's just printing:

http://roproxy.tk/catalog/json?Keyword=DJ Earworm&Category=9&ResultsPerPage=2

1: table: 1CFE5280

Audio

2: table: 1CFE56A0

Audio

When theirs more values in the table:

[{"AssetId":187411559,"Name":"DJ Earworm - Summermash 120 seconds","Description":"Audio","Url":"/DJ-Earworm-Summermash-120-seconds-item?id=187411559","PriceInRobux":"","PriceInTickets":"","Updated":"1 month ago","Favorited":"1 time","Sales":"22","Remaining":"","Creator":"FireFume","CreatorUrl":"/User.aspx?ID=30719032","PrivateSales":"","PriceView":0,"BestPrice":"","ContentRatingTypeID":0,"AssetTypeID":3,"CreatorID":30719032,"CreatedDate":"\/Date(1416187543210)\/","UpdatedDate":"\/Date(1416187543223)\/","IsForSale":false,"IsPublicDomain":true,"IsLimited":false,"IsLimitedUnique":false,"MinimumMembershipLevel":0},{"AssetId":162880181,"Name":"DJ Earworm - Mash Up for What ","Description":"Audio","Url":"/DJ-Earworm-Mash-Up-for-What-item?id=162880181","PriceInRobux":"","PriceInTickets":"","Updated":"6 months ago","Favorited":"2 times","Sales":"67","Remaining":"","Creator":"tigerwhit4","CreatorUrl":"/User.aspx?ID=40632244","PrivateSales":"","PriceView":0,"BestPrice":"","ContentRatingTypeID":0,"AssetTypeID":3,"CreatorID":40632244,"CreatedDate":"\/Date(1403570650790)\/","UpdatedDate":"\/Date(1403570667263)\/","IsForSale":false,"IsPublicDomain":true,"IsLimited":false,"IsLimitedUnique":false,"MinimumMembershipLevel":0}]

Script:

function GetValues(Table)
    for i,v in pairs (Table) do
        for _,k in pairs (v) do
            return k
        end
    end
