Hi,
I have used the INDEX and MATCH functions together for many months with no problems, however today it is returning some incorrect values and I cannot see what the problem is. I have attached a spreadsheet with an example of the data and the formula I am using.
Basically I have identified individuals (column A) which have 2 or fewer corresponding numbers in column B. I would like excel to return the value in column C which corresponds to the correct ID and Order number. Column H (order 3) should always return a #N/A value however (for example) ID number 81 (which only has 1 order) keeps returning three values. This problem disappears if I remove the number 8's in column A.
Any help would be much appreciated.
Thanks,
Suzanne
