In my index function, every time I try "flask run" it outputs that error (jinja2.exceptions.TemplateSyntaxError: expected name or number). Everywhere I've checked most people have been saying it's a syntax error but I can't quite catch it.

index code in application.py:

@app.route("/", methods=["GET"])
def index():
    rows = db.execute("""
        SELECT symbol, SUM(shares) as total_shares
        FROM transactions
        WHERE id = :user_id
        GROUP BY symbol
        HAVING total_shares > 0;
        """, user_id=session['user_id'])
    quotes = {}
    grand_total = 0
    for row in rows:
        stock = lookup(row["symbol"])
            "symbol": stock["symbol"],
            "name": stock["name"],
            "shares": row["total_shares"],
            "price": usd(stock["price"]),
            "total": usd(stock["price"] * row["total_shares"])
        grand_total += stock["price"] * row[total_shares]
    users = db.execute("SELECT cash FROM users WHERE id = :user_id", user_id=session["user_id"])
    cash = users[0]["cash"]
    grand_total += cash
    return render_template("index.html", quotes=quotes, cash=usd(cash), grand_total = usd(grand_total))

index.html code:

{% block main %}
<table class="table table-striped">
                <th>Price Per Share</th>
                <td colspan="4"></td>
                <td>{{ grand_total }}</td>
            {% for quote in quotes %}
                    <td>{{ quote.["symbol"] }}</td>
                    <td>{{ quote.["shares"] }}</td>
                    <td>{{ quote.["price"] }}</td>
                    <td>{{ quote.["total"] }}</td>
            {% endfor %}
                <td colspan="4"></td>
                <td>{{ cash }}</td>
{% endblock %}

You can't use two dictionary conventions at once. Either you can use quote.symbol or use quote["symbol"] in place of quote.["symbol"]. This should fix this particular error.

Hope this helps. If it does then please check the tickmark.
