Index - results in the last week/following week from 2 tabs

I'm brand new at working with the INDEX and MATCH functions, but I think they are the key to what I'm trying to do.

I'm tracking meetings for a number of sales people. I'm using 2 tabs for different types of sales, each tab listing the date of a sales meeting and adjacent, the name of the company. With hundreds of entries now, I wanted to add an INDEX to a summary page that will return results for meetings that happened in the last week and another for those set for the following week.

I've uploaded a sample spreadsheet. I played around with a few things before posting but couldn't find a close enough match in other threads to really get a handle on this. Thanks in advance for any help!

example worksheet.xlsx

to make this easy, i added a helpe column in sheet2, column A and used =WEEKNUM(B2) to find the week number

then use this to find what you need. change the +1 to -1 for last week
=VLOOKUP(WEEKNUM(TODAY())+1,Sheet2!$A$2:$C$6,3,FALSE)

not sure if this is somethng you could work with (or modify), but i created a pivot table for you. it is based on the week number. take a look and let me know what you think?
