Hello, I need help with code.

I have a macro that I use to process each calling card account's information.

A B C D
etc.
Date Number_dialed Location Duration

all columns have the same number of rows, but this number changes depending
of the amount of calls made from each account.

I have set the fixed range in my macro from 2:3800, but most of the time the
number of raws do'nt exceed 1000

Is there a way to just process the number of raws in each account instead of
going the full 3800?

Your help will be grately apreciated

Regards
