Hi, I checked System Preferences and found that I'm set for English and the comma appears in the Numbers area. On further checking, I tried again to get the thousands separator and this time I selected the entire column in my table. I was surprised to see the comma miraculously appear where it should. But also, where it wasn't supposed to in the same column. In the column, in random cells, I entered the year 2013 as a date. By selecting the entire column, the year 2013 turned into 2,013.00. So, I guess my new problem is: how to I keep the thousands separator in the entire column without changing these random 2013 cells? I hope you have a thought how to do this. Best regards, Mel
