What does it mean the Range and the Valid value on the Datafiled panel?
Answer
Range: the set of allowed values, that you can enter in the cell of the field
Example: 1 - 10 (values between 1 to 10), you cannot enter 11, 55 ...etc.
Enter the range of datafiled

What happens if the entered value is unsuitable?

Suitable value for range 1 - 10

Valid value: the set of allowed values, witch already exists in the field and witch you can choose from
Example: 1,2,5 you cannot enter 11, 55, you need to select from the existing three values (1,2, 5)
6 is unsuitable value if the selectable values are 1,2 and 5
