To restrict an input value to greater than 30 and less than 50, where should the validation be attached?

• A. Create a validation formula and attach it at the element eligibility level to validate the minimum and maximum of the input value at the time of entry.
• B. Create a validation formula and attach it at the element level to validate the minimum and maximum of the input value at the time of entry.
• C. In the element definition, enter minimum and maximum for the input value.
• D. Create a validation formula and attach it at the element input value level to validate the minimum and maximum of the input value at the time of entry.

Answer: (D)

Attach the validation formula to the element input value level because you want the constraint to apply to the specific value a user is typing and to be enforced at the moment of entry. By placing it here, the system evaluates the value as it’s entered and rejects anything outside the range 30 to 50 (since you want strictly greater than 30 and strictly less than 50), before the value is saved.

Placing the validation at the element level or in the element definition would affect the element more broadly and not necessarily focus on the user’s current input, so it wouldn’t reliably enforce the range during entry. The element eligibility level governs whether a value can be processed at all, not the numeric bounds of the input value. Therefore, the correct placement for this specific input-range check is the element input value level.
