Index & Match Formula with Unique Values bases on a criteria

Hi,

I'm exploiting Ck76's job.

In B4

=IFERROR(IFERROR(INDEX(Forecast!$B$3:$B$9,MATCH(0,IF($B$3=Forecast!$C$3:$C$9,COUNTIF($B$3:B3,Forecast!B$3:$B$9),""),0)),INDEX(Actual!$B$3:$B$9,MATCH(0,IF($B$3=Actual!$C$3:$C$9,COUNTIF($B$3:B3,Actual!$B$3:$B$9),""),0))),"")


In B11

=IFERROR(IFERROR(INDEX(Forecast!$B$3:$B$9,MATCH(0,IF($B$10=Forecast!$C$3:$C$9,COUNTIF($B$10:B10,Forecast!B$3:$B$9),""),0)),INDEX(Actual!$B$3:$B$9,MATCH(0,IF($B$10=Actual!$C$3:$C$9,COUNTIF($B$10:B10,Actual!$B$3:$B$9),""),0))),"")


Formulae need array status before to be copied down.
