using variables to select multiple rows using a macro
 

I am trying to use 2 different variables and either the ROWS or RANGE command
in a macro to select a continuous block of rows. I want to copy this block
from one sheet to another sheet. I have been trying to use the following
syntax with no avail: ROWS(firstrownumber,lastrownumber).Select I also
tried using:
RANGE(firstrownumber:firstrownumber,lastrownumber: lastrownumber).Select I
have to use a variable, because the actual row numbers I will be copying and
pasting will change every time I run the macro. I can make it work if I only
select and copy one row at a time, but in one of my sheets I need to select
and copy 2880 rows of data, and doing that one at a time takes about 5
minutes. Any suggestions would be very much appreciated. Thanks.
