Hi @yaminikoduri333 , 

You can achieve this with the Onchange client script

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

var listCollector = g_form.getControl('your_varaible_name_of_list_Collector'); // Get the list collector variable
var selectedOptions = listCollector.getSelectedOptions(); // Get the selected options from the list collector
var count = selectedOptions.length; // Get the length of the selected options array
// Check if the count is greater than one
if (count > 1) {
  g_form.setValue('Your _varaible_name_setting_the_count',count);
}  
}

Hi @Sai Shravan,

Thank You for the kind response. I tried this and i am getting below error.

There is a JavaScript error in your browser console.

As per my requirement, I want to display a variable if the count of list collector variable selections is more than 1.

Could you please help.

@Sai Shravan @akin9 Thank You for the kind replies. 

Finally From the reference of above suggestions i made it.

Below is the working approach.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var theValue = g_form.getDisplayValue('list_collector_field'); //newValue.toString();
var list = theValue.split(",");
var count = 0;

for (i = 0; i < list.length; i++) {
//g_form.addInfoMessage("This should be the list collector value " + list[i]);
count++;
}
if(count == 0 || count == 1){
g_form.setMandatory('variable_name2', false);
g_form.setDisplay('variable_name2', false);
//g_form.addInfoMessage('Count:'+count);
g_form.clearValue('u_priority');
}

if(count >= 2){
g_form.setDisplay('variable_name2', true);
g_form.setMandatory('variable_name2', true);
g_form.setValue('u_priority',1);
//g_form.addInfoMessage('Count:'+count);
}
