Not allowing duplicate records
 

Hi

I have a workbook that has several worksheets. I have a MASTER where
I record full details (where one customer could have multiple entries)
and another (DATA) where I have transposed only required data from the
master for a report.

There are 2 things I was wondering if it was possible.

1. If Customer A needs their details to be entered on the MASTER 3
times - can I have a formula that will automatically fill some of the
details to that row?
Example: I am entering Customer A in row 3 and I want information
from cols A & C in row 1 to fill the relevent cells in my sheet.

AND

2. Once an entry has appeared in DATA, information for the other
entries wont come into the data sheet from MASTER.

Example: So what has happened is in the DATA sheet I have transposed
the values from Cols A, D & F for customer A in row 1 but I now don't
want information from row 3 to appear.


(Hope this is clear - I'm confused!)

Example (MASTER):

A B C D E F
1 CustomerA 7 9 X L 6
2 CustomerB 6 7 Y R 4
3 CustomerA 8 7 Y P 6
