# Look up formula in Excel 2010 table

I am looking to generate a table (see ‘table’ sheet) which will lookup a wind direction (eg N, NE, WSW etc) together with a wind speed range (eg between 0 – 5 knts) on a separate sheet of data and count the number of times these paramters are met.  In other words on ‘Table’ sheet cell C5 formula to lookup the specified wind direction (N) in the table row(s) and the specified table column wind speed(s) (0 – 5, 5-10 etc) knots and return the number of occurrences for the given direction and speed ranges. attempts at using vlookup have failed.

In cell L5 on the same ‘Table’ sheet I am also looking to calculate the average speed for the various specified wind direction and combined speed ranges.

How might it be possible to dynamically change this table by selecting a specific time period such as year or month(s)?? to alter the various occurence values ?

The attached use of COUNTIFS may do the first job.

We may be looking at a second and third question for the other two, just to keep the diferent issues seperate.

NOTE: you are missing the column for 10-20

Steve, thanks  - COUNTIFS works a treat and cheers for noting obvious omission.

Let me know if need ask separate questions regarding other queries but feel relevant to this one workbook and wanted to be clear on what was required from outset in case maybe impact on how resolved.  The plots are already dynamic - with the workbook using name ranges.

I have added the formula for average using AVERAGEIFS.

I have added a second table to demonstrate the addition of date selection.
( I thought a second table may be clearer to see the changes made )
