Word 2010 - checkboxes with automatic autofil

Hello All:

I'm creating an Word Document and have 7 separate tables ( 1 table attached for reference ).  I am using 'autofield' for the auto fill so after the separate 7 tables ; It would autosum to equal on an separate table.  

My problem is I have checkboxes that when checked, need to update the 'autofield' with the appropriate number. I've used multiple macros & nothing worked so I've deleted all macros and starting fresh so any help would be greatly appreciated.  

I've also attached 2 examples.
attachment.png = Orange circle is autofield needed for autosum
example1.png = Checked 5 and autofilled #5
example2.png = Checked 3 and autofilled #3
