wrong, different credits, currently it is not recording them, but it is displaying the banners, so it is working.

how do you get exposures? And when it is recording credits, how will you get them?

When you display other people's banners, each view is a credit towards having your banner display onto other people's sites.

The coding currently does not display these but it is working, end of story.

so, exposures are how many times it has actually been shown?

Yep, as the word "exposure" suggests, it is how often the banner has been exposed.
