VLOOKUP and INDEX

My system is using XP Pro with MS Excel 2007. I have spreadsheet I'm trying to use as a status sheet. See attached spreadsheet. There is a format control that has my projects listed. Once a project is selected my expectation is to have all (currently most) cells to auto populate. There is a project called Rehab Kirkuk Museum-CERP and when I select this everything populates exactly as I wanted it to. Next I select another project, like the first and all is fine. But when I select another different project than the Rehab Kirkuk Musem project nothing happens. Selecting a different project each time results in nothing. Only when I return to the Rehab Kirkuk Museum-CERP does everything populate again. In the next selection is fine as well, but after that nothing works correctly. What is wrong with my setup? I suspect my Index and Vlookup functions are somehow having difficulty with my data. How do I fix this? See attached spreadsheet.
