MS Excel Objects Lock Row based on Value working with Other Objects

I have programming, with major help from others, that works great for two separate workbooks. The problem is that I can't seem to have them both work within the same workbook and I don't know why.

We have a large contact database (4800 rows) workbook with a lot of sorting macros. I use the following to allow the user to double-click a cell to select or de-select a contact. This is under the Excel Objects, Sheet1 (MASTER):

In another workbook, I tested the following for locking a particular row if an 'X' is placed in Column AZ (end of contact data). This is under the Excel Objects, Sheet1 (Sheet1):

In the Database file, I have certain rows that identify the contact's category that I would like to have locked. All other cells can be changed. If I copy over the 2nd code to the database file, it doesn't work correctly. Instead it locks all of the cells and prompts the message box regardless of an 'X' in Column AZ. Can these two not co-exist or what is this newb doing wrong?

Thanks!

Anybody? Would really appreciate the help!
