Will you please attach a SMALL sample Excel workbook(s) (10-20 rows of data is usually enough)? Please don't attach a picture of one (no-one will want to re-type all your stuff before starting).
(pictures of expected result - see also p2 below) are already posted)
1. Make sure that your sample data are truly REPRESENTATIVE of your real data. (If trere are typical cases like: all unique values/duplicates could occur, day/night, nobody present/several persons at once, before/on/past due, etc. - please show them all or at least indicate in text) The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired solution(s) is/are also shown (mock up the results manually).

3. Make sure that all confidential/restricted information (either personal or business) like real e-mails, social security numbers, bank accounts, etc. is removed first!!

To attach an Excel file you have to do the following: Just before posting, scroll down and press Go Advanced button and then scroll down and press Manage Attachments link. Now follow the instructions at the top of that pop-up screen.

This should get you going in the right direction

No problem, as Andy's suggestion worked fine.
But if you have no idea -let me put some light on why I asked for attachment with sample workbook (of course I could prepare on, but you altlready did, when preparing screenshots.

I believe it's fair if you (asking person) do all "family doctor/assistant/nurse work" (prepare patient for operation, collect documentation, may be even do anaesthesia, ... and we (those, who answer), we only do the real operation (well, may be also stitches )

Anyway, as I said - now we are all happy, because "your patient" is in good health again
