Shopify Fix Needed

Hi I had a developer make some changes to my site to block users from taking advantage of a FREE item multiple times. He added this code on my mobile theme but not my add to cart button is disabled for all products. If you know how to fix this please let me know. div> {% for item in [login to view URL] %} {% if [login to view URL] == 5305266182 %} {% assign disabled = "disabled" %} {% endif %} {% if [login to view URL] == 5461942022 %} {% assign disabled = "disabled" %} {% endif %} {% endfor %} {% if settings.display_quantity_dropdown %} <div class="selector-wrapper"> <label>Quantity</label> {% if flag == "true" %} <input id="quantity" type="number" disabled = "disabled" name="quantity" value="1" class="tc item-quantity" /> {% else %} <input id="quantity" type="number" name="quantity" value="1" class="tc item-quantity" /> {% endif %}
