Building Summary Report - Find Multiple Matches in a table

Hello,

In a earlier post I attached a file for reference that probably wasn't very helpful.

An updated file has been attached.

What I'm needing help with is populating the return table with dates and values that pertain to two columns in the dataset. You'll see in the criteria box, i'm looking for records that reference a particular type if they pertain to a particular lot. Records that match the criteria, need to be returned to the return table. You'll notice in the Return Table, in the date column, i'm using a formula built with the index function. It's inadequate because it's finding all the lot records that are WM141. I want to limit the findings to Lot WM141 & Type = Purchase in this example.

Thanks in advance for the help.
