Tricky Formel (counting days in combination with lookup)
 

Hey Guys,
I try to figure out a formel which I need for counting the days between
days.
I have two tables with the following structure
2003 2004
Comp Est. Start Date Company Est. Start Date

BT 23/03/2003 Dell 22/04/2004
Cable 24/05/2003 BT 22/05/2004
Virgin 22/06/2003 Virgin 28/06/2004

What I want do do now is to count the days between the Estimated Start
Dates if a company is listed in 2003 and 2004 (BT and Virgin).
If the company is not listed in 2003 and 2004 the cell should be empty
(Cable)
I think the formule must contain vlookup sum and data array function.
The attachment contains the table.

Thank you in advance

Christoph

Christoph,

This should work if you name your 2003 range as YR03 and
your 2004 range as YR04.

=IF(ISERROR(VLOOKUP(A16,YR04,2,FALSE)-VLOOKUP
(A16,YR03,2,FALSE)),0,VLOOKUP(A16,YR04,2,FALSE)-VLOOKUP
(A16,YR03,2,FALSE))

Christoph,

Sorry should reread before I post. A16 refers to a cell
that contains the Comp (Dell, Virgin, BT).

Hope this helps.
