Pset7 Finance, Sell problem with POST requests

Question

My problem is that I'm not getting any value back from my select form. I pass a list of stocks to the jinja template via return render_template("sell.html", stocks=stocks) and on the sell.html page I have the select form set up as

{% block main %}

<form action="/sell" method="post">
    <div class="form-group">
        <select class="form-control" name="symbol" form="sell">

            {% for stock in stocks %}
            <option value="{{ stock.symbol }}">{{ stock.symbol }}</option>
            {% endfor %}

        </select>
    </div>
    <div class="form-group">
        <input class="form-control" name="shares" placeholder="Amount" type="number"/>
    </div>
    <button class="btn btn-primary" type="submit">Sell</button>
</form>

{% endblock %}

This works so far as it shows the stocks correctly on the drop-down menu, but when I try to get the selected value back via symbol = request.form.get("symbol") the returned value is None. (tested by passing the symbol back into the template and just printing it out, it showed None for all selected options).

Answer 1

Solution was to remove the unnecessary form=sell from the select tag as I was already working in one form without noticing.
