From LimeSurvey Manual
Maximum sum value (max_num_value)
This setting is available in the multiple numeric and numeric array input questions. When this attribute is set, the input value(s) (depending on the type of question) must meet this criteria - the (sum of) number(s) has to be smaller than the value you type in this box. Otherwise, the respondent will not be able to submit her answer.
- Any integer value above 0
- Any number
- Any SGQA code
- Any question code (variable name)
- Any equation, using ExpressionScript syntax, without surrounding curly braces.
- Setting a value of 20 would mean that the total value of all numbers entered in all input boxes for this question may not exceed 20. Totals of 21 would not be allowed. A total of 15 would be acceptable.
