HI
Have worked with a sheet for several years. I just copy the sheet and use eg. 2011 and use most of the cell values I have before entered.
This time I did the same for 2011 and cells have changed the input , to . And many cells just have the ###### . I have adjusted the size but the cell have changed to a date cell instead of standard and text cell.
When I mark the row or a few cells just to change the comma to point the value I have entered before is gone and instead the date is shown as a number. This frustrate me a lot as I need to manually enter previous value first by changeing the cell to a text cell and then the old value.
If I had just one or two hundred cells with this it would be ok. But my different sheets contain thousands of cells with different values.
What could be wrong and what to do?

Appreciate any suggestions I can try
