Hello i use this code for my shopify store but it wont let me click on the previous category. Can anyone make it the others clickable?

{% unless template == ‘index’ or template == ‘cart’ or template == ‘list-collections’ %}

Home

{% if template contains ‘page’ %}
›

{{ page.title }}

{% elsif template contains ‘product’ %}
{% if collection.url %}
›

{{ collection.title | link_to: collection.url }}
{% endif %}

›

{{ product.title }}

{% elsif template contains ‘collection’ and collection.handle %}
›

{% if current_tags %}
{% capture url %}/collections/{{ collection.handle }}{% endcapture %}

{{ collection.title | link_to: url }}

›

{{ current_tags | join: ’ + ’ }}

{% else %}
{{ collection.title }}
{% endif %}

{% elsif template == ‘blog’ %}

{% if current_tags %}
{{ blog.title | link_to: blog.url }}
