Put the sheet names in A1:A5 then:
=SUMPRODUCT(SUMIF(INDIRECT("'"&A1:A5&"'!F2"),4303,INDIRECT("'"&A1:A5&"'!G2")))
If you only have 4 sheets for example then use A1:A4 or maybe use a named range. I dont know what you mean by its a date on the tab??
=SUMPRODUCT(SUMIF(INDIRECT("'"&TEXT(V7:V43,"d mmmm yyyy")&"'!"&"F2"),"*4303*",INDIRECT("'"&TEXT(V7:V43,"d mmmm yyyy")&"'!"&"G2")))
Oh i see. It will just be excel converting your dates to true dates as you put them into A1:A5. Just format those cells to text then input the sheet names.
