Blank Screen When using Echo '<DIV>..</DIV>'

I am currently trying to enable a select view within the page. However, I have encountered an issue. The page will display a list of items/objects when the following PHP code is used:

<?php

echo elgg_view_title($vars['entity']->title);
echo elgg_view('output/longtext', array('value' => $vars['entity']->description));                              
echo elgg_view('output/longtext', array('value' => $vars['entity']->my_options));
echo elgg_view('output/tags', array('tags' => $vars['entity']->tags));
echo elgg_view('output/my_options', array('my_options' => $vars['entity']->my_options));

However, the page would be blank when I add in the following code ontop of the above code:

echo '<DIV> <html>
    <body>

        <select>
            <option value="A">a</option>
            <option value="B">b</option>
            <option value="C">c</option>
            <option value="D">d</option>
        </select>

    </body>
</html> </DIV>'

Therefore, the entire code would look something like this:

<?php

echo elgg_view_title($vars['entity']->title);
echo elgg_view('output/longtext', array('value' => $vars['entity']->description));                              
echo elgg_view('output/longtext', array('value' => $vars['entity']->my_options));
echo elgg_view('output/tags', array('tags' => $vars['entity']->tags));
echo elgg_view('output/my_options', array('my_options' => $vars['entity']->my_options));

echo '<DIV> <html>
    <body>

        <select>
            <option value="A">a</option>
            <option value="B">b</option>
            <option value="C">c</option>
            <option value="D">d</option>
        </select>

    </body>
</html> </DIV>'

Can anyone, pls help and point out what's seems to be wrong? Thank you

Solution

You are missing a ; at the end of the echo statement.

Replace

echo '<DIV> 
<html> 
<body> 
<select> 
<option value="A">a</option> 
<option value="B">b</option> 
<option value="C">c</option> 
<option value="D">d</option> 
</select> 
</body> 
</html> 
</DIV>'

with

echo '<div> 
<select> 
<option value="A">a</option> 
<option value="B">b</option> 
<option value="C">c</option> 
<option value="D">d</option> 
</select>
</div>';

as it is not the correct structure of HTML
