I Share one spreadsheet with some friends around the world. They have English Operating System. I Have Spanish Operating System.

I've noticed that we have a lot of problems because Zoho's spreadsheet sometimes accept to me "."  (dot) like the separator of numbers, but sometimes it rejected to me and I must use "," (comma) as the separator.

When I save the spreadsheet and some friend around the world want see my changes, he will find the numbers without separatos (an only entire number) or like a text field instead a number. 

The formulas does not work, The date formats are wrong.

I Have many troubles. Can You help me to solve this problem?

Regards
