Edit Field
Fields have a number (position), that must be
unique within a template. The fields are ordered by this number,
but the sorting order is alphabetic, i.e. position 10 comes
between 1 and 2. If you have more than 9 fields, you should change the
position numbers and start with 10 instead of 1.
You may choose a numerical type for the field, if only digits are allowed for input.
