# Excel - INDEX Function Problem - Expert Solution

Question description:
This user has given permission to use the problem statement for this blog.

I need to use a lookup value that is the result of a formula, (in this case a date) and lookup or match an element in an array (which is a date.. same format as the resultant) and either access the value in the next right cell or use as an index to retrieve it. I have used "=MATCH(C4,Demand,0)" in which C4 is a formula that returns a date in format as an example ... "16-Apr-18" .. and Demand is a series of columns with dates in the same format and sequenced .. I get "#N/A" .. not the value I need and there is an exact date match in the lookup array ....

if I have an array of dates that are sequenced called DEMAND and I have a cell that is a formulae that results in a date (same format as in the array), what either MATCH or VLOOKUP will work as MATCH(c4,Demand,0) returns a #NA

User 13/04/2018 - 01:24

Excelchat Expert 13/04/2018 - 01:32
yes concept is right
Excelchat Expert 13/04/2018 - 01:33
But the format between c4 and demand is not right I guess
Excelchat Expert 13/04/2018 - 01:33
may be c4 is returning text instead of date format
