I am using the following formula below that works fine however I would like
to modify it such that rather than tell it to go to worksheet 1401
(INDEX('[0910-1400-WB-Actual.xlsx]1401'!$D$11:$Q$135) I would like it to say
look for the any sheet in the workbook using a reference say B1.

Note: in B1: b12 say I would list all the tabs in the workbook.. Is this
possible

thanks



=IF(OR(F$1=1,INDEX('[0910-1400-WB-Actual.xlsx]1401'!$D$11:$Q$135,MATCH("TOTAL
FUEL",'[0910-1400-WB-Actual.xlsx]1401'!$C$11:$C$135,0),MATCH(F$1,'[0910-1400-WB-Actual.xlsx]1401'!$D$9:$Q$9,0))=0,0),INDEX('[0910-1400-WB-Actual.xlsx]1401'!$D$11:$Q$135,MATCH("TOTAL
