However, if the numerical range is limited to a very few options, you should consider whether a radio
button field or a drop-down list would not be a better item type.
Input impossible

These rules define the circumstances under which individual questions must or may not be
answered. The standard example is the rule Input impossible, if... . This rule always requires the input of a supplementary condition (see below). The condition may e.g. be that another field has been
answered with YES. The combination of the rule and condition is then e.g.: "Input impossible, if
question 2 has been answered pregnancy= YES".

If pregnancy= YES has been specified for question 2 and an entry is made in the item to which the
rule Input impossible has been assigned, the form is reloaded with an error message on the affected
item after saving the form. This field is evaluated as completed after saving.

In contrast, the rule Input not required, if... only affects the completion status (as described under 2),
but does not trigger an error message in the above example.

If all of a form's fields have "Input not required, if..." rules which are met or "Input not required" rules,
and the form is saved without input, it is regarded as complete and is displayed accordingly.
