Thank you. I have changed to div, but the problem still is there.
By
<div id=”Target”></div> (Placed inside a wrapped text)
I mean that I have put <div id=”Target”></div> in the place of the page which is wrapped by the Collapse-o-Matic. When I press on the link to jump to the necessary place in the page, the page unwraps but I arrive at the incorrect location. If I follow the link again, I arrive at the correct location. But at some point I arrive at the incorrect location again.
