  {# Requesting balance entry for member from balances index #}
  {% set balanceEntry = guild.indexes.balances.get(targetMember.id) %}
  {# Updating the balance #}
  {% do balanceEntry.update(newBalance) %}
  
  Balance of {{ targetMember }} has been set to {{ newBalance }}!
{% else %}

  {# Calculating requested page number #}
  {% set wasLast = parameters.get('page.isLast') %}
  {% set pageNum = (parameters.get('page.number')) ?: 0 %}
  {% if component.id == 'next_page' and not wasLast %}
    {% set pageNum += 1 %}
  {% elseif component.id == 'prev_page' and pageNum > 0 %}
    {% set pageNum -= 1 %}
  {% endif %}

  {# Requesting the page from the index, saving some if its data that will be used to calculate next page number #}
  {% set page = guild.indexes.balances.getPageOf(pageNum, 2, 'DESC') %}
  {% do parameters.store('page.number', page.number) %}
  {% do parameters.store('page.isLast', page.isLast) %}
  {% set isEmpty = page.totalPages <= 0 %}
  
  {% if not isEmpty -%}
    {# If we have any data in the index, show page content #}
    Page {{ page.number + 1 }} of {{ page.totalPages }} (total {{ page.totalElements }} entries)
    {% for entry in page %}
      {% set number = loop.index + page.number * page.size -%}
      {{ number }}. <@{{ entry.key }}>: {{ entry.value -}}
    {% endfor %}
  {%- else -%}

### Pass parameters using the parameters store

Source: https://docs.juniper.bot/en/message-templates/advanced/tags
