hook_block_view not passing information - drupal-7

Question

I am trying to build my first custom module in Drupal 7. It is a block form for the user to search a DB table for customer information. I've created both the module and info files. My module appears under the modules and blocks section, but when I add the block to Content, the subject and content aren't being passed from my hook_block_view. So, instead of the form being displayed, it just shows the block title and body. Can someone tell me what I'm missing?
<?php
/**
*#file
*
*/
/** Implements hook_block_info().
*
*/
function searchEngine_block_info(){
$blocks = array();
$blocks['searchEngine_form'] = array (
'info' => t("Applicant Search"),
'cache' => DRUPAL_CACHE_GLOBAL,
);
return $blocks;
}
/** Implements hook_block_view().
*
*/
function searchEngine_block_view($delta = ''){
$block = array();
switch($delta) {
case 'searchEngine_form':
$block['subject'] = t('Applicant Search');
$block['content'] = drupal_get_form('searchEngine_form');
break;
}
return $block;
}
function searchEngine_form($form, &$form_state) {
$form['searchOptions'] = array(
'#type' => 'select',
'#title' => t("Select how you would like to search for an applicant."),
'#default_value'=> variable_get("gwf", true),
'#options' => array(
'gwf' => "GWF".t(" Number"),
'email' => t("Email"),
'name' => t("Name"),
'phone_number' => t("Phone Number"),
),
);
$form['data'] = array(
'#type' => 'textfeild',
'#required' => TRUE,
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Submit'),
);
return $form;
}
function searchEngine_submit($form, $form_state) {
if(isset($form['data'])){
if($form['searchOptions'] == "name"){
$name = preg_split("/[\s,]+/", $form['data']);
$result = db_query('SELECT * FROM tls_active_applicants WHERE first_name = '.$name['0'].' AND last_name = '.$name['1']);
}else{
$result = db_query('SELECT * FROM tls_active_applicants WHERE '.$form['searchOptions'].' = '.$form['data']);
}
print_r($result);
}
}

Passing a renderable array here is fine:
$block['content'] = drupal_get_form('searchEngine_form');
I've just tested your code and the form appears fine for me:
Now we know the code works it makes me wonder if it is just some css or something hiding it?
I would also install the devel module as it will help with debugging.
The you could use this code:
function searchEngine_block_view($delta = ''){
$block = array();
switch($delta) {
case 'searchEngine_form':
$block['subject'] = t('Applicant Search');
$form = drupal_get_form('test_form');
dpm($form); // call to dpm here to log if you are successfully getting the form at this point
$block['content'] = $form;
break;
}
return $block;
}
