Multiple Matches - Index/Match

hello -

I have attached a simplified workbook which contains my problem.

Worksheet "BI" contains the data.
Worksheet "Main" displays data based on the given date (A3).

When "Main" is active, I would like the user to be able to enter a date into (A3) and have all corresponding 'Widgets' displayed in (A4) and all corresponding 'Units' to be displayed in (B4). If a second 'Unit' matches the given criteria (date) i would like that to be displayed in (A5) and (B5) respectively.

I am able to do this when only one 'Unit' matches the given criteria.
=INDEX(BI!A2:BI!A21,MATCH(A3,BI!B2:BI!B21,0))

Notice how Ship Date (BI!B10, and BI!B11) are the same, 7/25/2007. If I were to type in 7/25 to (Main!A3) I would like to see both 'Widgets' displayed along with their respective 'Units'.

BI0009 | 5
BI0010 | 5

Hope this makes sense, apologies if this has been answered before--i've searched but i can't find anything.
