I'm curious to know and wondering if somebody could please
explain why the comma near the end of this formula does
not return an 'entered to many arguments' type of error
message? The formula gives the same result in my work with
or without the , before the ))

INDEX($A$1:$F$1,MATCH(LARGE(A7:F7,2),A7:F7,))

TIA
