This function LARGE(K5:K38,34) causing error because you do not have 34th largest value in range K5:K38. What is you desired output from LARGE(K5:K38,34)?

# Re: Index function and #NUM! error

because I want to get entire 34 rows of the table,and sorted values of column K from highest to lowest and using Filter function to get  out 3 columns from 6 first columns, but I dont know what the function to get that.That's why I use it.

I writed a formula again:

=INDEX(SORT(I5:N38,3,-1),SEQUENCE(34),{1,2,3,4,5,6})

the value is sorted fail

Can you give me some advicing

Thank you

# Re: Index function and #NUM! error

@small_village The formula in column K returns a hyphen when the VLOOKUP doesn't find a match. Change that to the number 0 (no quotation marks). Then the formula in X5 will sort correctly.

By the way, since you have a modern Excel version that supports dynamic arrays, why not skip using VLOOKUP. Better to look into XLOOKUP. Add more flexibility and no need for IFERROR as XLOOKUP includes an argument [if_not_found].

Thank you Riny

It is done

How can the Xlookup returns array what I expect the same Index function

# Re: Index function and #NUM! error

@small_village Nothing wrong with that index function. I was referring to the formulas in column K in the earlier schedule, where VLOOKUP could be replaced by XLOOKUP.
