Google Analystics mixes the reports of my web sites

I am new with GA.
I have three websites with three domains.
A week ago, I opened one account and created a profile for each website,
and inserted the tracking code to every page in all the web sites.
Now, after a week, when I look at the reports, I see on one profile
several web pages from another profile.
The profiles get mixed.
What have I done wrong?

 

What you've done wrong is put the same code on all 3 domains.
Generate new code for each one.

 

Yes, I did put the same code for all the web sites.
How do generate now , at this point, new codes?

 

Yes I was going to recommend resetting them up. I tried Yahoo's analytics and a couple other ones both were not as powerful as Google's. Its all matter of setting them up.

 

Thanks,
I fixed the code manually, I hope that it will work fine.
