The addchoice screen (addchoice.html) code follows below. I included
it just in case something might be wrong with it that could be related
to or causing this problem, because some of its code is also doing
some new things that I've not done before, so there are likely errors
in it as well. Here's the code:
<h1>Add Poll Choice Screen</h1>
<form action="/polls/addchoice/" method="POST">{% csrf_token %}
{% if ccount and pquestion %}
<p><strong>There are currently {{ ccount }} choices for the Poll
Question {{ pquestion }}?</strong></p>
{% endif %}
{% if message %}<p><strong>{{ message }}</strong></p>{% endif %}
<br /><br />
<label>POLL QUESTIONS:</label>
<select name="polls" id="polls" type="select-one">
{% for poll in polls %}
{{ poll.question }}
{% endfor %}
</select>
<br /><br />
<input type="submit" value="addchoice" />
<br /><br />
{% if newchoice %}
<p>NEW CHOICE ADDED WAS={{ newchoice }}</p>
{% endif %}
</form>
Thanks for the help.
