I have a workbook that includes the following sheets; Grades, reading, math
comp, applied math, language and combined math. The combined math sheet is a
table and it contains the scores for math computation in cells b2: aa28 where
the scores are listed as 0 to 25 correct in increments of 1. The combined
math sheet also lists the scores for applied math in cells a3:a28 listed in
increments of 1 from 0 to 25.

To look up the grade level of a combined math test you find the number
correct in the math computation score from b2:aa28 and then match it against
the applied math score found in a3:a28 . The intersection of that row and
column returns a grade level equivalent.

I have the math computation score in cell d2 of the sheet called grades and
I have the applied math score in cell E2 of the grades worksheet. I need a
function to lookup and return the score to cell I 2 on the grades work
sheet.

i think I need an index and match function :
I can't seem to get the syntax correct .

I have

=index(combined math!$a$2:$aa$28,match(Grades!$d$2,combined
math!$a$2:4aa$28,),match(Grades!$e$2,combined math!$a$2:$a$28,))


can you help? I would really appreciate it

Thanks
Tom
