hi Pere. maybe just a VLOOKUP?
=VLOOKUP($A8,DATA!$B$7:$BN$15,COLUMNS($F9:F9)+1,0)

or if the dates are not in order, then:
=VLOOKUP($A8,DATA!$B$7:$BN$15,MATCH(F$1,DATA!$B$1:$GF$1,0),0)

if you're supposed to add up the numbers (like in New House Construction Costs), then maybe:
=SUMIF(DATA!$B$7:$B$15,$A8,INDEX(DATA!$C$7:$BN$15,,MATCH(F$1,DATA!$C$1:$BN$1,0)))
