Referencing the Proper Dates

[apetnuch]

I'm having an excel challenge. I need to find/create a formula that knows what cells I want to reference based on dates. So, for example:

old Dates old data New dates data
5/4/2011 4 4/1/2011 10
6/14/2011 5 5/1/2011 13
7/25/2011 8 6/1/2011 12
9/4/2011 14 7/1/2011 15
10/15/2011 22 8/1/2011 16

How do I get excel to know that I want it to do 16 minus 14 because the new date associated with 16 (8/1/2011) falls between the dates 9/4/2011 and 7/25/2011?

I think this is what you're asking.
Put the formula =INDEX($E$3:$E$7,MATCH(1,IF($D$3:$D$7>G3,IF($D$3:$D$7<H3,1,0)),0))-INDEX($C$3:$C$7,MATCH(1,IF($D$3:$D$7>G3,IF($D$3:$D$7<H3,1,0)),0)-1) into cell G4 and CTRL+SHIFT+ENTER b/c its an array formula.

for some reason the whole formula didn't go through from my earlier post.

=INDEX($E$3:$E$7,MATCH(1,IF($D$3:$D$7>G3,IF($D$3:$D$7<H3,1,0)),0))-INDEX($C$3:$C$7,MATCH(1,IF($D$3:$D$7>G3,IF($D$3:$D$7<H3,1,0)),0)-1)

CTL+SHIFT+ENTER this formula b/c its an array formula.

=INDEX($E$3:$E$7,MATCH(1,IF($D$3:$D$7>G3,IF($D$3:$D$7<?XML:NAMESPACE PREFIX = H3,1,0)),0))-INDEX($C$3 /><H3,1,0)),0))-INDEX($C$3:$C$7,MATCH(1,IF($D$3:$D$7>G3,IF($D$3:$D$7<H3,1,0)),0)-1)< p>
CTL+SHIFT+ENTER this formula b/c its an array formula.

If the formula contains the "less than" character the forum software interprets it as an html code character and sometimes causes text to be truncated.

Try putting space characters on both sides like this...

...IF(range < this...


</H3,1,0)),0))-INDEX($C$3:$C$7,MATCH(1,IF($D$3:$D$7>

thank you T.Valko...
