You could possibly incorporate them as sub-reports into a main report, or you could direct the command button to print all of the reports. There is no other simple way of "merging" the reports. You dont say if they have the same recordsource, and if so, whether you are attempting to rationalise the four reports into one?
Hope this helps, Cheers,
