m,aking highest value in one colum match the same cell in another colum

the burnt orance cell is
=LARGE(C167:C196, 1)
so i am picking up the largest cell value in the colum

I then want to select colum a and match this 60 to it so it should read 3.3 which is cell A180 yet it reads cell a196 which is 6.4 and it is confusing the hell out of me

and I am using =LOOKUP(C157,A167:D196,A167:A196)in cell d157 to do this
please advise

all i want to do is get a value for the highest cell in colum C starting at CELL 168 ONWARDS AND MATCH COLUMS A to it
cant do it help!!!!!
