@Surendra6 You can write an onChange client script on the first variable. As soon as user makes any changes on the first variable, the onChange script would get called. 

Inside the script, you can get the value of the first variable, if it is a comma separated string sys_ids you can use string.split(',') to get an array of the sys_ids. 

Finally you can get the count using array.length and show the same count in the second variable.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
var stringArray = newValue.split(',') ;

g_form.setValue('second_variable',stringArray.length);
}    

Hope this helps.

Hello @Surendra6 -

Please write OnChange Client script and try below code:

var variable1 = g_form.getValue('//variable1_name');
    var count = 0;
    if (variable1) {
        var variable1Array = variable1.split(','); 
        count = variable1Array.length;
    }
    g_form.setValue('//variable2_name', count);
