You need to tell us more specifically about your situation if you want us to tell you what you've done wrong.
Just continue submitting with a quality site and top ranking. And also more strategies to do so get on first page ranking. Make sure that all required info must filled.
Sometimes I have #11 for a keyword and the day after I have #23. That happens, this is normal don't worry. And this is not going to affect your PR either.
If your site is new, like you said then you are probably in the Google honeymoon stage where Google gives a boost to new sites, eventually your site will begin to drop to lower SERP levels, so now is time to start building backlinks so you can crawl back to the top!
Dance baby dance! Google is always doin the dance. Don't sweat the changes, good or bad. Just keep building good content and making a better site.
its perfectly normal for new sites to jump around the rankings, this is known as google dance, it will eventually stabilize.
try to maintain quality backlinks . may be your competitors are getting more strong . once you get ranking you need to keep maintaining it .
