# Return date associated with maximum value

This question relates to the same data set from a previous question: http://www.experts-exchange.com/Software/Office_Productivity/Office_Suites/MS_Office/Excel/Q_28363479.html

For each "Site", I would like to obtain the value for "SampDate" associated with the maximum values in columns H, I, and J. The results should appear in columns K, L, and M.

I think that VLOOKUP may be able to do this, but I am unsure of the proper syntax.

Many thanks in advance for any potential solutions!

Hello dougflr,

I used this "array formula" in K5 confirmed with CTRL+SHIFT+ENTER and copied across 3 columns and all the way down.

=IF(AND(\$J4="",\$J5<>""),INDEX(\$C5:\$C200,MATCH(MAX(IF(\$B5:\$B200=\$B5,H5:H200)),H5:H200,0)),"")

That will give you the SampDate associated with the max value on the first row of average data for each site.

To "array enter" a formula you can put the formula in a cell, select that cell and press F2 key to select formula - now hold down CTRL and SHIFT keys and press ENTER. If done correctly curly braces will appear around the formula. If you change the formula this needs to be re-done....but only for first formula - it can then be copied

See attached

To clarify, the ranges of data from which to search for the maximum values for each site are in columns H, I, and J. For example, for the first site (04CEF-1) I would like to be able to identify the SampDate associated with the maximum value from the range of values in rows 5 through 90 for each column H, I, and J.
