9. google_ad_client = "ca-pub-XXX";
10.  
11. /* Replace AAA, BBB, etc. with the respective Ad Slot IDs */
12. if ( adWidth >= 728 )
13. google_ad_slot = ["AAA", "728", "90"]; /* Leaderboard 728x90 */
14. else if ( adWidth >= 468 )
15. google_ad_slot = ["BBB", "468", "60"]; /* Banner (468 x 60) */
16. else if ( adWidth >= 336 )
17. google_ad_slot = ["CCC", "336", "280"]; /* Large Rectangle (336 x 280) */
18. else if ( adWidth >= 300 )
