Help - multiconditional index formula

Hi guys,

here I'm again to claim for your help.

The issue is that I've to do an INDEX, but I want it to be MULTICONDITIONAL.

So, into the attached excel you can find, sheet (LIST_VALUES_TO_RETREIVE):

The A column contains the date which I intend to consider as a condition ("> 01-12-2013" (EUROPE SETTINGS))
The D column contains the document type which I intend to consider as a condition (only docs started by IMP, via MID function

The column N, contains the Serial number for which I will search and retrieve the value in column U.

Into the sheet (LIST_VALUES_TO_SEARCH), a few examples of serial numbers for which I want to have the WO nr, but this time based on other criteria’s such as DATE and TYPE of document.

Regards
CMP
