Update chart data from drop down list

[Artos90]

I re-created an excel worksheet I want to use to track a breakdown of hours for equipment activity per month. I have created named range (cell C1:N1) to populate a drop down list to select a specific month. I am trying to get the chart to change to show data for a specific month when it's selected from the drop down list (in cell P2). I have used the OFFSET and MATCH functions in the name manager but for some reason it does not change the chart when I change the month. I am not sure what I am missing? I inserted a link to the file below.


Any help would be greatly appreciated

I appreciate your quick feedback. I must apologize if I did not clearly state my issue. I do not understand what you mean by "D5 is not a drop down." The drop down list for the months is located in cell P2. The offset and match functions are working correctly to locate the month and activities associated with the month. I just can't figure out how to get the chart to update the values to match the month in cell P2.

I meant my D5 is not a drop down - it could be but for quickness I just typed in mar. The 5 numbers below are obtained by offsetting from the cell above jan, matching mar in the column jan to april, and going 1,2,3,4,5 columns to the right. If the chart is based on the 5 values produced by me, then the chart can only be mar. If I changed it to feb, the chart would be feb.
