Create Unique List & Summarize All Associated Values

I have a list of sales events that ran at various venues, together with how many people attended and how much revenue was brought in by sales. This data is arranged by week. One venue will never have more than one event per week, but different venues may have sales events on the same week.

My table looks like:

In reality this list could be thousands of rows long.

“Event week” is the calendar week of the event. “Weeks open” shows for each event how many weeks that venue has been open (may or may not be useful!).

What I need to do is to be able to pick a number of weeks (preferably changeable by entering into a cell) and have a list produced of each venue that has run for at least that many weeks, and the sum of people and sales in those first X weeks. My idea of output, if the user input “2” as the number of weeks would therefore look something like:

Note that
1)only venues that have run at least 2 meetings are shown in the output
2)even if venue has run over 2 meetings, only people and sales figures from the first 2 are summed up and displayed.

In this case. Later on I need to produce a frequency chart/histogram grouping the results into categories, but I know how to do this as long as I can get to the step before – but wanted to mention it in case there are shortcuts.

Have been battling with this with pivots, database functions, array formulae etc. for a long time.

Attached is the spreadsheet with sample data. The red table is the part I am stuck on. The solution has to work in Excel 2003.
