findMinIn2SForms( )

Find the minimum value of a given data item in all instances of the repeating section in a two-section form. This function works only for numeric fields.

For this function you can only use number-type questions. You cannot use drop-downs, radio buttons, or checkbox values as function parameters or as a target.

This is an aggregation function. The rule is run for each instance in the case where the target is on a repeating section of a two-section form.

Syntax

findMinIn2SForms(formInstance,'variable')

Parameters

Note:

It is allowed to reuse variables passed into this function elsewhere in the rule expression, however you must add the variable as a parameter using single quotes.

Parameter	Required/Optional	Description
formInstance	Optional	Indicates the form instance in which the search for the minimum value is to be performed. If formInstance is null and variable is in flat section, the flat section of all instances is searched. If formInstance is null and variable is in a table row, all table rows in all instances are searched. If formInstance value is provided, the search is across the table rows of the specified instance only.
variable(s)	Required	Item variable to check, passed in using single quotes.

Return value

Numeric value that constitutes the minimum value across all instances or "0" if no minimum can be found.

Examples

Example 3-64 Find the minimum value of the "weight" number item across all repeating section instances in a two-section form in a visit

// Given 5 repeating section instances in a two-section form with "weight" item containing values of "150, 200, 250, 300, 350"
return findMinIn2SForms(null,'varWeight');
 
// returns 150
