Hi,
I'm studying a sheet that someone else has made with the prospect of
creating a new sheet in the same format but with different data. Can anyone
explain to me what is going on in these vlookups, specifically the ROW
references? How does this work? Thanks!

=VLOOKUP(F$1,L.1_d!$1:$65536,ROW(18:18)-ROW($4:$4),FALSE)
=VLOOKUP(F$1,L.1_d!$1:$65536,ROW(31:31)-ROW($4:$4)+1,FALSE)
=VLOOKUP(F$1,L.1_d!$1:$65536,ROW(62:62)-ROW($4:$4)-2,FALSE)
