Reverse Two Way Lookup With Duplicates

I have an appointment schedule shaped like a table and I need to extract data from it into a sub table. The schedule has date column headers, time row headers, and the intersection of the date and time headers is a cell with a patient’s name. There are duplicate patient names in the schedule. The extract table should list the patient names vertically and next to each patient name should be a list of dates and times. The time and date for a single appointment should be contained in one cell.

For simplicity, I will not use dates and times in my example, but instead I will use letters.

Schedule looks like this:

Date Column headers are as follows: B1 = m, C1 = n, D1 = o, E1 = p
Time Row headers are as follows: A2 = q, A3 = r, A4 = s, A5 = t, A6 = u, A7 = v
The cells that contain patient names are: B2 = Jo, C3 = Sioux, C4 = Sioux, D2 = Sioux, E3 = Chin

The extract table looks like this:

Column headers are as follows: B20 = # App, C20 = App 1, D20 = App 2, E20 = App 3
Row headers (patient names) are as follows: A21 = Chin, A22 = Jo, A23 = Sioux
The cells that contain times and dates are: C21 = “r, p”, C22 = “q, m”, C23 = “r, n”, D23 = “s, n”, E23 = “q, o”, where the first letter is a time and the second letter is a date.

A while back I posted a question about this sort of reverse two way lookup:

Since then I have encountered the problem of the patients showing up in more than one time slot on a single day and also showing up in the schedule on more than one day. The formulas I am using are not working. So in my example, the trouble I am having comes from the fact that Sioux’s name shows up in more than one time slot for one day and also he shows up on more than one day.

If it is easier to see the table with dates and times, the data is here:

Schedule looks like this:
Date Column headers are as follows: B1 = 1/8/2010, C1 = 1/9/2010, D1 = 1/10/2010, E1 = 1/11/2010
Time Row headers are as follows: A2 = 8:00 AM, A3 = 9:00 AM, A4 = 10:00 AM, A5 = 11:00 AM, A6 = 12:00 PM, A7 = 1:00 PM
The cells that contain patient names are: B2 = Jo, C3 = Sioux, C4 = Sioux, D2 = Sioux, E3 = Chin

The extract table looks like this:
Column headers are as follows: B20 = # App, C20 = App 1, D20 = App 2, E20 = App 3
Row headers (patient names) are as follows: A21 = Chin, A22 = Jo, A23 = Sioux
The cells that contain patient names are: C21 = 9:00 AM, 1/11/10, C22 = 8:00 AM, 1/8/10, C23 = 9:00 AM, 1/9/10, D23 = 10:00 AM, 1/9/10, E23 = 8:00 AM, 1/10/10
