Put the sheet names in M1:M12 and use

=SUMPRODUCT(--(T(INDIRECT("'"&M1:M12&"'!C6:CX6"))="Pass"),--(T(INDIRECT("'"&
M1:M12&"'!C7:CX7"))="Open"),N(INDIRECT("'"&M1:M12& "'!C10:CX10")))

conditions to be verified on 2 row ranges from C6 to CX6 and C7 to
CX7across
all 12 sheets and calculate the matching on the range C10 to CX10, When I
give


IF(AND(October:Septemeber!C6:CX6="Pass",October:Se ptemeber!C7:CX7="40-06"),S
UM(October:Septemeber!C10:CX10))
