First, check your regional settings and make sure that the decimal separator is set to dot (point), and the list separator is set to comma. Here is what it looks like on my PC:

If the decimal separator and list separator are already set that way, check File > Options > Advanced.

Under Editing options, make sure that the check box 'Use system separators' is ticked.
