local variable 'search_keyword' referenced before assignment

Question

I have been working on a search form and it's giving me this error when i open the url or submit the form. I am watching a codemy django tutorial and the only thing that is different is that i have some code for pagination i don't know if that's what is affecting it.

base.html

<div class="header-search-wrapper novis_search">
                    <form method="POST" action="{% url 'listing' %}"  name="searchform">
                        {% csrf_token %}
                    <div class="custom-form">
                            <label>Keywords </label>
                            <input type="text" placeholder="Property Keywords" name="search"/>
                            <!-- <label >Categories</label>
                            <select data-placeholder="Categories" name = "home_type" class="chosen-select on-radius no-search-select" >
                                <option>All Categories</option>
