Exception: System.Web.HttpParseException (0x80004005): The code block is missing a closing “}” character. Make sure you have a matching “}” character for all the “{” characters within this block, and that none of the “}” characters are being interpreted as markup.
Here is my code.

@using System.Linq
@using System.Xml.Linq
@using umbraco.MacroEngines
@using uBlogsy.Web.Extensions
@using uBlogsy.Web.Helpers
@{
    if (Model.NodeTypeAlias != "uBlogsyPost")
    {
        return;
    }
    
    // get item count
    int count = int.Parse(@Parameter.ItemCount);
    if (count == -1)
    {
        count = int.MaxValue;
    }

    // can be uBlogsyPostTags, uBlogsyPostCategories, or empty string (gets both)
    string relatedAlias = @Parameter.RelatedAlias;

    // get number of items to match
    int matchCount = int.Parse(@Parameter.MatchCount);

    
    // get all posts
    var sorted = NodeHelper.GetPosts(Model.Id);
    
    List<DynamicNode> nodes;
    if (!string.IsNullOrEmpty(relatedAlias))
    {
        nodes = NodeHelper.GetRelatedPosts(Model.Id, relatedAlias, sorted, matchCount);
    }
    else
    {
        // get both tags and categories
        List<DynamicNode> relatedByTags = NodeHelper.GetRelatedPosts(Model.Id, "uBlogsyPostTags", sorted, matchCount);
        List<DynamicNode> relatedByCategories = NodeHelper.GetRelatedPosts(Model.Id, "uBlogsyPostCategories", sorted, matchCount);

        nodes = new List<DynamicNode>();
        nodes.AddRange(relatedByTags);
        nodes.AddRange(relatedByCategories);

        // get distinct, and order by date
        nodes = nodes.Distinct().OrderByDescending(x => x.GetProperty("uBlogsyPostDate").Value).ToList();
    }
    
     if (nodes.Count > 0)
     {
        <div class="uBlogsy_related_posts_container uBlogsy_bottom_border">
            <h2>
                Related posts</h2>
            <ul class="uBlogsy_related">
                @foreach (DynamicNode n in nodes.Take(count))

                    </li>
                }
