I have this formular:
=SUMPRODUCT(--(Tables!$C$2:$C$2979=$A4),--(Tables!$D$2:$D$2979=$B4),--(Tables!$E$2:$E$2979="Yes"))

but it is showing as an error. Iknow there is no errors in there but when I
click the Trace Error option I get a little "Table" icon and I don't know
what that is or what it means.
Any ideas?
