Highlight a recordpost in a report depending on content

[PeterG]

How do I create a light yellow backgound (or highlight) only on record posts in my report which fullfill a certain condition? If [Order Nr] > 0 then light yellow backgound fo the whole record.

Look at conditional formatting. In Design view, select the items in the Detail section of the report to be highlighted, and go to the "Format" dropdown menu and then to "Conditional Formating...". This will let you set up the desired format under the desired set of conditions.
