So you need to collect all projects with sDate at least in the range (2016-10-01 . 2016-10-01) and eDate at least in the range (2016-10-20 . 2016-10-20) to include the above project. A collection with the ranges (2016-10-1 . 2016-10-31) and (2016-11-1 . 2016-11-30), for example, would return all projects which started in October AND ended in November 2016. The ranges are inclusive btw. - Alex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
