ExpressionEngine 1.6.9: LG Polls module; display question and assign poll id from control panel

Question

Hi friends,

I'm a real newbie at EE. Having trouble about LG Polls module

I followed the steps from the official module guide. I set up everything as it was told at doc. You can see below my code (taken from doc again). the current code below displays answers, I also can vote, everything is working great. It just doesn't display the question :/ any idea what can be the problem? Appreciate helps!!!

Also, do we have to give specific entry_id="29" via code? there should be a way to define this via control panel? a non-technical person can not assign new poll in this way since they will need to edit code and they easily can mess with codes :/ How can we assign poll via control panel?

Template code

{exp:weblog:entries}
  {exp:lg_polls:poll entry_id="29" precision="1" return="/blog/"}
   <p>{poll_question}</p>
    {if can_vote}
      {poll_form}
        {if has_voted}<p>You have already voted in this poll, however you can vote again.</p>{/if}
        <ul class='lg-polls-answers'>
          {poll_answers}
          <li class='a-{answer_count}'> 
            <label for='lg-polls-answer-{answer_id}'>{answer_input} <span class='answer'>{answer}</span></label>
          </li>
          {/poll_answers}
        </ul>
        <div class="alignCenter"><input type="image" src="{site_url}/images/btn_submitpoll.png" alt="Vote" /></div>
      {/poll_form}
    {if:else}
      {if has_voted}<p>Thanks for voting in this poll.</p>{/if}
      {if restricted}<p>Sorry, You are restricted from voting in this poll.</p>{/if}
      {if expired}<p>This poll ended on {expiration_date}.</p>{/if}
      {if yet_to_begin}<p>This poll is yet to begin. Voting opens on {entry_date}.</p>{/if}
    {/if}
    {if show_results}
      <div class='lg-poll-results' id='lg-poll-results-29'>
        <ul class='lg-polls-answers'>
        {results_answers}
        <li class='a-{answer_count}'>
          <span class='answer'>{answer}</span>
          <span class='answer-total-votes'>{answer_total_votes} votes &nbsp;&nbsp; <b>{answer_percentage}%</b></span>
        </li>
        {/results_answers}
        </ul>
        <div class='poll-total-votes'>Total Votes: {poll_total_votes}</div>
      </div>
    {if:else}
      {if show_results_after_poll && has_voted}The results of the poll will be made available on {expiration_date}{/if}
      {if never_show_results && has_voted}The results of this poll will be made public at a later date.{/if}
    {/if}
  {/exp:lg_polls:poll}
{/exp:weblog:entries}
