Compare two similar tables

[Gary Crisp]

I am attempting to compare two tables to find the differences. One table is a
compiled list of invoices billed and the other is my record of what we have
received. I'm looking to compare the two to find the difference. I would also
like to append the invoices billed with each months' invoices. Any kelp would
be greatly appreciated. Thanks

I would like to compare one table against the other to find "missing
invoices".
