“too many arguments” means the number of “,” , “(” & “)” is not right. Just double check for each if(a,b,c) and and(a,b,c) to have enough brackets, data/arguments and comma.
In your code, there is a total of 73 pieces of “(” and only 71 “)” . Thus, it is clear that some “(” or “IF(” was not closed properly. The corrected version :
=IF(AND(S284<>"",R284<>"",A284<>B284),INDEX(RATE, MATCH($A284,BID_NO,0), MATCH($R284,RATES,0)), IF(AND(S284<>"'',R284="",A284<>B284),INDEX(SHIFT_INFO, MATCH($A284,SHIFT_BID,0), MATCH(L$4,SHIFT_HEADER,0)), IF(AND(S284="",R284<>"",INDEX(SHIFT_INFO, MATCH($B284,SHIFT_BID,0), MATCH(L$4,SHIFT_HEADER,0)) <> INDEX(SHIFT_INFO, MATCH($A284,SHIFT_BID,0))),INDEX(RATE, MATCH($A284,BID_NO,0), MATCH($R284,RATES,0)), IF(AND(S284="",R284="",INDEX(SHIFT_INFO, MATCH($B284,SHIFT_BID,0), MATCH(L$4,SHIFT_HEADER,0)) <> INDEX(SHIFT_INFO, MATCH($A284,SHIFT_BID,0))),INDEX(SHIFT_INFO, MATCH($A284,SHIFT_BID,0), MATCH(L$4,SHIFT_HEADER,0)),""))))
That should be sufficient.
Hope that solves.. (:
p/s: you may use notepad++ or other coding tools to help “highlighting” the brackets pair too.
