Dear Affordsol,
I should smash my head as I had a #Value in col D, thats why the
=SUMPRODUCT(--(Data!B:B=A8),--(Data!C:C=LEFT(B8,3)),(Data!D:D)) didn't work,
after I errase the #value, now all back to normal. Anyway thanks again for
your help.

Maybe You should use:
=SUMPRODUCT(SUMIF(Data!B:B,A8,Data!D:D),SUMIF(Data !C:C,LEFT(B8,3),Data!D:D))
- #NUM!

HI,
I have sumif formulas which work fine, but when combine them as sumproduct,
result is #NUM!, why?
=SUMIF(Data!B:B,A8,Data!D:D) - answer
=SUMIF(Data!C:C,LEFT(B8,3),Data!D:D) - answer
=SUMPRODUCT(--(Data!B:B=A8),--(Data!C:C=LEFT(B8,3)),(Data!D:D)) - #NUM!
