I think the problem is with your data table in sheet2. You may have
values in column B which look like percentages but which are actually
text values, so when you try to do some arithmetic on them in B13 you
get the #VALUE error. You will need to change the values in your table
to numbers.

Incidentally, your formula in B9 looks up the table A2:B65 in Sheet2,
but in B10 you are looking at A3:B66.

Hope this helps.

This formula calcualtes the % of hearing loss in the right ear and the left
ear then uses a formula to calculate the % of total bilatearl hearing loss. *
The formula in B13 multiplies the lesser % of the right vs. left ear by 5
then adds the greater % and divides by 6. * I get a #VALUE! in B13. *If I
manually enter the percentages in B9 and B10 OR in B12 and B13, then B13
calculates correctly but it apparently won't calculate if I have a formula in
B9/B10 or B12/B13. *Help!
