Update table on another sheet with information on ACTIVE SHEET based on column search.

I'm in DIRE need for help, and I need help as soon as possible. I'll ask... if no one can help me on this here, can someone at least advise me on where I can go to get this help, as I cannot find the solution I'm after anywhere on this site or any other. If I had hair, I'd be pulling it, trying to figure out how to do this.

So... What I have is a sheet that is copied periodically from some source sheet, and on this sheet is a table. This sheet is called "Onsite Checklist Template" and it's table is titled "Checklist". I also have another sheet called "Loggers and Initial Notes" which has a tabled titled "Record", and then finally a title sheet call "Proj Details".

To clear this intro up - The sheets, in their order, is: "Proj Details", "Loggers and Initial Notes", "Onsite Checklist Template". The tables: "Record" on "Loggers..." and "Checklist" on "Onsite..."

When the user wants to make a new site visit, he/she fills in the requested date and then selects a button on "Proj...". When this button is selected, it copies the table data on "Record" and puts it on "Checklist", then inserts a new worksheet tab, always in the 3rd position (the title is based on the site visit date in which the user entered), which is a copy of "Onsite...". Now we have another sheet with a table called "Checklist1", and upon another new site visit, there will be another worksheet with "Checklist2", and so on.

On the "Onsite..." worksheet, there is a button on it which also gets copied with the worksheet so that every new worksheet has this copied "Checklist ???" and this button. I'm looking for a macro that, when the button is selected, will bounce the active sheet's table "Checklist ???" off of "Record" and make changes as needed.

"Checklist ???" data range is B11:M20 (the header is on row 10); "Record" data range is B29:Q78 (the header is on row 28); Column headers are titled the same, just that "Record" has 4 extra columns, 3 in the middle and 1 on the end. "Checklist ???" columns 1-12 to "Record" columns 1-7, 10-12, 14-15. The search criteria is the 4th column in both tables ("Trk #").

I need the macro to do the following:

1. If it finds a match, then update "Record" as needed with data from "Checklist ???", changing whatever cell is different in the row that contains the matching "Trk #", so long as the cell on "Checklist ???" is populated (i.e, if a cell on the target row of "Record" has a value, but it's blank on "Checklist ???", then "Record" wins; if it's blank on "Record", but populated on "Checklist ???", the Checklist wins. If both populated but different, then Checklist wins.
2. If a "Trk #" exists on "Checklist ???" but is not on "Record" then add the line to "Record" (the 1st empty row, table size remains)
3. I see no need for any "delete" at this time.

My concerns:

1. The last column on record (column #16) is the filtering column for the worksheet copy event and needs to be left alone (it's formulated to produce a "Yes" or "No")
2. I would like the ability to adjust table sizes if needed without modifying the macro
3. The table rows on "Checklist ???" will not be changed, deleted, or altered in any way by the macro.

Thank you in advance to ANYONE that can help me, or point me in the right direction.

I didn't originally post it because I can't really do anything like "Put this cell's data"... "Over here", on the worksheet. But if it helps to get responses from anyone other than someone telling how to get responses faster, then I'm willing to give it a shot. So here it is.
