4 days before i had created new campaign.i that campaign not show any clicks all the status shows zero. but in billing show 20 clicks ..what is the problem i am facing?
Your keywords may have zero clicks, but as mikeavery11 mentioned your Display Network may have received clicks.
Are your keywords on Broad match? If so it is potentially other variations of keywords that are getting your clicks. You need to click on your campaign, then go across to keywords. Have a look in the middle screen and you should see, "See all search terms" and click "All" and there you should see what other keywords are providing you with clicks. Hope that helps.
