Hi I am copying data from one sheet and pasting it into another
workbook.

Range("A1").Select
Selection.CurrentRegion.Select
Selection.Delete
Rows("1:1000").Select
Selection.Delete
Workbooks.Open Filename:="p:\pro65\csr01.xls"
Range("A1").Select
Selection.CurrentRegion.Select
Selection.Copy
ActiveWindow.Close
Range("A1").Select

An example of the dates Before and After follows:
Note I require DD/MM/YYYY format
Note some cells have " - -"
BEFORE
- -
- -
1/11/2004
18/10/2004
10/08/2004
15/12/2004
10/12/2004
13/12/2004
12/11/2004

AFTER
- -

11/01/2004
18/10/2004 PROBLEM
8/10/2004 PROBLEM
15/12/2004
12/10/2004 PROBLEM
13/12/2004
11/12/2004 PROBLEM

The problem:
If DD < 12 the the format changes from DD/MM/YYYY to MM/DD/YYYY

PS if I copy and paste the data manually I don't get the problem.
