Hi @aditya2810 

It would be better to write a onChange client script on 'how_many_more_times' as below.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var field = g_form.getField("mrvs"); // multi variable set name
    if (field != null) {
        field.max_rows_size = newValue; // number of rows allowed to be entered
    }
}

 


Thanks,
