Please Help, Very Important!

I have a blog site, and they gave me a code for AdSense approval. They say you need to add this code to your site, but I couldn't figure it out. My page is visited by hundreds of people daily, with 90,000 visitors in 25 days. I want to get AdSense approval. I have applied multiple times, but they keep rejecting my applications, saying there are things to fix. I can't find where to add this code. If anyone understands, please contact me. I will never forget your help.
