编写条件：
C1:=IF(CODELIKE('002'),"399005$C",INDEXC); 指数:=IF(CODELIKE('300'),"399006$C",C1); C/REF(C,1)-1)*100>0.91>=(指数/REF(指数,1)-1)*100; 请问这样写公式问题出在那？>0.91这个没有起到做用？是为何，请高手指点编写方法：
IF(CODELIKE('002'),"399005$C",
IF(CODELIKE('300'),"399006$C",
IF(CODELIKE('600'),"999999$C",
"399001$C"))),COLORFFFFFF,NODRAW;
指数涨幅差:(C/REF(C,1)-指数/REF(指数,1))*100,COLORFFFFFF,NODRAW;
