Creating a updating master list from multiple tables

Skywriter, seems that a bug is rearing its ugly head here. In the attached version, you will see that I have done some formatting changes to the last version to put the final touches on it. The bug that I am running in to now is that, in its current form, when I update a cost in tblDay1 and run the report, the row on that report for the activity from day 2 disappears. Press it again and the button disappears and the data from the two tables on the cost page disappears. I have tried it with updating costs on other tables/days and other ways to get the bug to replicate, but, for now at least, it seems to just be for when I am updating a cost of tblDay2.

Any ideas? Thanks again for the help!
