Why not just use 2 SUMIF(...), one per sheet, then add them up?
: =SUMIF(...)+SUMIF(...)

=SUMIF(Sheet1!B20:B39,"<999",Sheet1!E20:E39) works fine for Sheet1, but I
can not get
=SUMIF(Sheet1!B20:B39,'Sheet2!B3:B49',"<999",Shee t1!E20:E39,'Sheet2!E3:E49')
to include the range or sum_range from sheet two.

Thanks John
