Hard Min, Hard Max Field

Used with Date Entry, Numeric Entry, Time Entry, and Slider Entry question types.

The HardMax and HardMin (hard maximum and hard minimum) fields define the range of acceptable answers for certain questions. The maximum defines the upper limit, and minimum the lower one. The range is valid only for questions that require a numeric answer or a date. Ranges are never specified for an alphabetic answer. These fields can be used in conjunction with SoftMax and SoftMin fields. (See, SoftMax and SoftMin field.)

Range specifications

Range specifications in HardMax and HardMin fields (and the SoftMax and SoftMin fields) can be either static range checks or dynamic range checks. The two forms are distinguished below:

Static

or absolute, are expressed in absolute terms such as integers, dates, times;
Dynamic

or relative, are expressed in terms of the contents of a symbol. (See, Save Symbol field.) This capability permits the computation and specification of valid ranges during execution of the survey, e.g., date-of-birth, refers to the value that is stored in the symbol {date-of-birth}. The fixed-symbol {*curdate} is used by the Manager to refer to the current date and always contains the current date. When refering to symbols in the text of questions, the symbols' names must be enclosed in percent signs ({ }), e.g., {date_of_birth} or {*curdate}).
