Drop Down List Dependant Formula
 

Hi,

I have a drop down list where a user can select the month (cell I6).
I also have a data set on another sheet like this:

jul;aug;sep;oct;nov...Total;YTD Total
100;250;350;420;530...Total;YTD Total

Assume date range starts in A1 and figures start in A2. Also, the fiscal year starts in July, not January.

What I'd like to have happen is that depending on the month selected from the list - for that selection to drive a YTD sum calculation/function, i.e. If the user selects October from dropdown list - then the YTD total sum will only include months upto and including October only (i.e. July, Aug, Sep, Oct).

Thanks in advance.
Happy to help with further details.

Thanks anyway. Have figured it out from another forum.
Answer for those interested:

=SUM("start of data range":INDEX("start of data range:end of data range,MATCH(dropdown list with months,start of month range:end of month range,0)))
