This question is related to What are some good ways to implement breadcrumbs on a Jekyll site? and I need to get the position from the loop. <meta itemprop="position" content="">

<ol class="breadcrumb list-unstyled" itemscope itemtype="https://schema.org/BreadcrumbList">
 <li class="breadcrumb-item" itemprop="itemListElement" itemscope
      itemtype="http://schema.org/ListItem"><a itemprop="item" href="/"><span itemprop="name">Home</span></a><meta itemprop="position" content="1"></li>
 {% assign crumbs = page.url | split: '/' %}
 {% assign crumbs_total = crumbs | size | minus: 1 %}
   {% for crumb in crumbs offset: 1 %}
    {% if forloop.index == crumbs_total %}
        <li class="breadcrumb-item active"itemprop="itemListElement" itemscope

        <li class="breadcrumb-item" itemprop="itemListElement" itemscope
      itemtype="http://schema.org/ListItem"><a itemprop="item" href="{% assign crumb_limit = forloop.index | plus: 1 %}{% for crumb in crumbs limit: crumb_limit %}{{ crumb | append: '/' }}{% endfor %}"><span itemprop="name">{{ crumb | replace:'-',' ' | upcase }}</span></a><meta itemprop="position" content=""></li>
    {% endif %}
  {% endfor %}
</ol>
</nav>

On line #12 Just add one. <meta itemprop="position" content="{{ crumbs_total | plus:1 }}"> Line # 16 already has the var, {% assign crumb_limit = forloop.index | plus: 1 %} So, on line # 18 you only need <meta itemprop="position" content="{{ crumb_limit }}">

{% if page.layout != 'home' %}
<nav class="breadcrumbs bootstrap hidden-sm-down">
<ol class="breadcrumb list-unstyled" itemscope itemtype="https://schema.org/BreadcrumbList">
 <li class="breadcrumb-item" itemprop="itemListElement" itemscope
      itemtype="http://schema.org/ListItem"><a itemprop="item" href="/"><span itemprop="name">Home</span></a><meta itemprop="position" content="1"></li>
 {% assign crumbs = page.url | split: '/' %}
 {% assign crumbs_total = crumbs | size | minus: 1 %}
    {% for crumb in crumbs offset: 1 %}
    {% if forloop.index == crumbs_total %}
        <li class="breadcrumb-item active"itemprop="itemListElement" itemscope
      itemtype="http://schema.org/ListItem"><meta itemprop="item" content="{{ site.url }}{{ page.url | relative_url }}"><span itemprop="name">{{ page.crumbtitle }}</span><meta itemprop="position" content="{{ crumbs_total | plus:1 }}"></li>
    {% else %}
{% assign crumbs_position = 1 %}
        <li class="breadcrumb-item" itemprop="itemListElement" itemscope
      itemtype="http://schema.org/ListItem"><a itemprop="item" href="{% assign crumb_limit = forloop.index | plus: 1 %}{% for crumb in crumbs limit: crumb_limit %}{{ crumb | append: '/' }}{% endfor %}"><span itemprop="name">{{ crumb | replace:'-',' ' | upcase }}</span></a>{% assign crumbs_postion = crumbs_position | plus:1 %}<meta itemprop="position" content="{{ crumb_limit }}"></li>
    {% endif %}
  {% endfor %}
</ol>
</nav>
{% endif %}
