Grab lowest date based on criteria

Ok, so you will you see 3 tabs for this example. The first tab shows everything I need to see, the 2nd tab is a list of all of the information, the third tab is just a list of all of the opportunities.

You will see on Tab 1, column C, this is the formula I thought would work, clearly it is not. What is needed is that in Column C, I need the lowest date from Tab 2, that meets the same criteria. For Example.

If on the 2nd Tab, Hollins University with the opportunity name, "2010 Six Campus Buildings", everything should show nothing, expect for under "100%" the date should read 3/5/2010.

Any help would be great!

What I meant by that, was the only field that should show up in that line is the 100% field, because that is the only one that meets the criteria.

What I want is for the first tab to summarize the information on tab 2. So, if you are looking at the first line:

Pilot Travel center 2010 Retrofits

Tab 2 shows that there are only things at 90% and 1 at 100%. Therefore, in the columns of 25%, it should be blank, 50%, should be blank, 75% should be blank, 90% will return the earliest date, which in this case would be 2/27/2010 and 100% should return 3/3/2010.

Does that clarify?

The second equation worked with little change, however, it is returning the highest date, not the lowest, thoughts? I'm trying to throw a MIN function into it.... no success yet.

Here is the updated file. You will notice that I will not return the MIN date for some reason. I tried the third equation and got nothing but errors. Please let me know if you see my mistake.
