Google Adsense? And web pages?

I don't really know where to put this, but I hope I put it in the right spot. I am sorry if I put this in the wrong spot. This is dealing with web pages.

I have been trying to use google adsense and for some reson it the ad want show up on my page, but the google search will show up. I have put the code in waited and it want show up, I have tried to refresh my page, that hasn't worked, I have tried creating a new ad and that hasn't worked. Can anyone help me. I don't know what else I have tried reading and reading, and watching videos and I am getting nothing.

Thanks for the help.

 

I did that and I am getting nothing but thanks for your time. I have been trying to find out what the problem is for a month now, I have contacted google, and they told me to check my host files, I did that, that didn't work, they asked was I using a software to block something, I forgot what it was, but that want it because I don't use software's like that. I have asked people on google adsense help, they can't help me, I have gone to other places and asked people and I can't find no one to help me, maybe a will find out soon, I am going nuts. This is supose to be easy, but I must be doing something. I have done everything they said to do, about using the code and all that. I am lost and getting mad at it.

Thank you so much for your help, and your advice Arie.
