Macro to sort an activity sheet by current week and current + last 1 and 2 weeks

Hi i have a sheet that looks like:

Row 1 to 8 contains general info and macro buttons, so all data starts from row 9.
In cell C2 i have todays date by =TODAY() as 13-nov-11
In cell C3 i have current week by =INT((C2-DATE(YEAR(C2-WEEKDAY(C2-1)+4);1;3)+WEEKDAY(DATE(YEAR(C2-WEEKDAY(C2-1)+4);1;3))+5)/7)

Column A have cut-off dates like 10.11.2011
Column B have Week no. auto from formula: =IF(ISBLANK(A9);"";INT((A9-DATE(YEAR(A9-WEEKDAY(A9-1)+4);1;3)+WEEKDAY(DATE(YEAR(A9-WEEKDAY(A9-1)+4);1;3))+5)/7))
Column C have disciplines like Mech, process, automation etc from a data validation list
Column D have activities this week
Column E have activities expected next week

I have 3 macro buttons that i want to filter:
Button 1: Show only current week + top rows 1-8
Button 2: same as above + current week -1 (aka current + last week)
Button 3: Same as above + current wwek -1 + current week 2 (aka current + last two weeks)

Also the code must differentiate between different years since activity will be 2-3 years long

I have this code to show current week but it dont show row 1 to 8 and it seems to have flaws since it shows not only current
