Single Page Visits is more than entries
Hello. I have a trouble with bounce rate counting. I use following formula: single page visits / entries. But when I'd built report with splitting on tracking code I see such picture:

You can see that BR (bounce rate) is more than 100%. Single Page Visits is more than entries. Could you help me with this problem:
1) Why bounce rate is so strange? Maybe problem is in formula.
2) Why single page visits is more than entries? Is problem in splitting or in something else?
Thanks
