Issue with Arrays/Match/Index

Here is my current formula I use to pull the latest live date for a customer out of a web query.

{=LARGE(IF(Table_owssvr_1[HQ Name]=B1,1,0)*IF(ISNUMBER(Table_owssvr_1[Live Date]),Table_owssvr_1[Live Date],0),1)}

B1 is the name of the customer. HQ name is column A and contains customer names.

This formula will give me the latest open date for the customer but it doesn't filter whether it was a live, closed, or customer on hold. The problem I am having is that I need to have this formula check one more column in that table to see that is matches "Live -3" before giving me the largest date. It is column C in the table "Status". If the data in the column says Live -3 for that customer, then I need it to pull the largest date from among multiple entries that say the "Live -3". The dates are in column L, "Live Date".

I've been attempting using match and index function but have had no luck. I appreciate any help.
