Hi Alex Many Thanks for helping me In Umazel starterkit SectionPortfolio.cshtml @itemCategoriesNoCommas -> error above

    //Get the ids and drop commas - those will be in the class attribute for script to work
                    string itemCategories = item.Categories;
                    string itemCategoriesNoCommas = itemCategories.Replace(" ", "").Replace(",", " "); 

   <div class="nf-item @itemCategoriesNoCommas @spacingClass">
                    <div class="item-box">
                        <a href="@item.Url" title="@item.GetPageTitleForMenu()">
                            <img class="item-container" src="@imageThumb" alt="@counter" />
                            <div class="item-mask">
                                <div class="item-caption">
                                    <h5 class="white">@item.GetPageTitleForMenu()</h5>

                                    @if (!currSection.DoNotDisplayCategories && !hideCategories)
                                    {
                                        <p class="white">@categoryNames</p>
                                    }

                                </div>
                            </div>
                        </a>
                    </div>
                </div>

Helper class portfolio helper

  public IEnumerable<DGenericCategoryItem> GetCategories()
    {

        IEnumerable<DGenericCategoryItem> categories = null;

        if (_hasCategories)
        {
            //Check if category is contained in at least one portfolio item's picker. If not, don't add to list since it's an empty category.
            categories = _categoryItems.AsEnumerable();
        }
        return (categories);
    }
