Dependent variable: Variable is dependent on number of users in list collector variable

[ChristineH85739]

Hello,

I have a list collector variable and an attachment variable. The attachment variable should only be visible and mandatory if the number of users in the list collector is more than 5.

Use an onChange Catalog Client Script similar to this:

function onChange(control, oldValue, newValue, isLoading) {
    var usrArr = newValue.split(',');
    if (usrArr.length > 4) {
        g_form.setDisplay('v_attachment', true); //attachment variable name
    } else {
        g_form.setDisplay('v_attachment', false);

This should also cover hiding the variable when the form loads, but if not create a similar onLoad Catalog Client Script, replacing newValue with g_form.getValue('user_list').split(',') where 'user_list' is the name of your list collector variable.
