Hi @Saib1 Please try below.

function onSubmit() {
    var groupMembers = g_form.getValue('add_group_members'); 
    
    if (groupMembers) {
        var memberCount = groupMembers.split(',').length;

        if (memberCount < 20) { /
            alert('You must select at least 20 members to add to the group.');
            return false; 
        }
    } else {
        alert('No group members selected. You must select at least 20 members to proceed.');
        return false;

Hi @Saib1 ,

You can write onsubmit client script and use below logic to prevent the form submission.

var str = g_form.getValue('add_group_members');
if(str.split(',').length <20)
return false;

Hi @Saib1 ,

How you can, you have to select user 1 by 1 and if you run script on onchange the it will be less than 20 user at a time. What is your business requirement.

Also you can use same script in onchange also just remove the return line and display message or clear field value.

@Runjay Patel

I tried the below script it was giving me the length as '1' if i did not select any value on the list collector

alert("hello");

var str=0;

var str = g_form.getValue('add_group_members');

if(str.split(',').length <20)

alert(str.split(',').length);

alert('This will allow only to select more than 20 members to be added in group');

return false;

}
