Hi,

I have 2 sheets with several fields.
on sheet1, i have new data and on sheet2 i have old data.

i would like to update 2 fields of sheet1 with data from sheet2.

for that i want to compare 3 fields, let's say C, D, E.

if C, D, E are equal on sheet1 and sheet2, so i want to copy data from
fields A and B (from sheet2) to fields A and B of sheet1.

for now i use selection.autofilter .....
on the 3 fields to compare, but with my 20,000 records, it's really slow
(on 3.1 Ghz CPU and 1 Ghz ram).

So i would like to know if exists another way how to do it and for sure
faster ?
thanka a lot for help.
