Common problem combining multiple sheets?

I'm fairly new to excel and completely new to the forum. I have a problem that surely must be a quite common one, but I've been searching high and low without finding what I'm after.

I have two spreadsheets.

Sheet 1 has two columns:

Date Incidents
02/11/06 200
02/18/06 360
02/24/06 240

Sheet 2 has two columns too:

Date Cost
02/11/06 436
02/12/06 229
02/13/06 610
02/14/06 374
02/15/06 450
02/16/06 56
02/17/06 450
02/18/06 450
02/19/06 436
02/20/06 450
02/21/06 341
02/22/06 654
02/23/06 782
02/24/06 336
02/25/06 742
02/26/06 582

I want to combine the two to get:
Date Cost Incidents
02/11/06 436 200
02/12/06 229
02/13/06 610
02/14/06 374
02/15/06 450
02/16/06 56
02/17/06 450
02/18/06 450 360
02/19/06 436
02/20/06 450
02/21/06 341
02/22/06 654
02/23/06 782
02/24/06 336 240
02/25/06 742
02/26/06 582

I'd be very grateful for any help. And when giving your answer keep in mind that I'm a bit of an excel newbie Thanks!

You have the dates in two sheets, which date do you want to use? Can you attach a sample workbook?

Thanks for your quick reply! I want to use the dates from spreadsheet 2. Note that all dates in the date column of sheet 1 are already present in sheet 2. Sheet 2 has one row for every day in its interval.

Solved using match and replace.
=INDEX(B:B;MATCH(A2;B:B;0))
=INDEX(C:C;MATCH(A2;B:B;0))
