are these 2 equivalent and if so, which is preferred? there are a few hundred of
these formulas in a workbook and i'd like to change the 2nd one to the first
one.

=T50/SUMIF($I$3:$I$20,I50,$F$3:$F$20)
=T50/(LOOKUP(I50,$I$3:$I$20,$F$3:$F$20))

Not at all. The LOOKUP only finds a single value, SUMIF finds multiple
values, and the LOOKUP array has to be in ascending order, SUMIF doesn't
care.

if there is only one occurance of I50 in the range I3:I20, then they would
be equivalent.

I don't have an opinion on which is preferred

ok, thanks tom. I3:I20 contain A thru R, so each value is unique. it's only
looking at a single character to determine the value in column F

in this case, I50 contains B, so it returns the value from F4.

is there a better way?

or how about this instead?

=INDEX(F3:I20,MATCH(I50,I3:I20,0),1)

sorry, hit send too fast
=T50/INDEX(F3:I20,MATCH(I50,I3:I20,0),1)

where I3 contains A, I4 contains B and I50 contains B

finds B in range f3:i20 then returns the value from F4 and then divides it by
T50

Given A - R ordered then

=T50/offset(F3,code(I50)-65,0)

for case insensitive

=T50/offset(F3,code(ucase(I50))-65,0)

You could do away with I3:I20
