My PHP File doesn't show up when i call a function - php

Question

Code:
<?php
require 'Controllers/MenuController.php';
$menuController = new MenuController();
if(isset($_POST['types']))
{
$menuTables = $menuController->CreateTypeTables($_POST['types']);
}
else
{
$menuTables = $menuController->CreateTypeTables("%");
}
$title = 'Menus';
$content = $menuController->CreateMenuDropdownList(). $menuTables;
include 'Template.php';
?>
Basically when i do it this way, my page doesnt anything, not even a echo
It doesn't even show my background pic from css
But when i exclude the function:
<?php
require 'Controllers/MenuController.php';
$menuController = new MenuController();
// if(isset($_POST['types']))
//{
// $menuTables = $menuController->CreateTypeTables($_POST['types']);
// }
// else
// {
// $menuTables = $menuController->CreateTypeTables("%");
// }
$title = 'Menus';
$content = "test";
//$menuController->CreateMenuDropdownList() . $menuTables;
include 'Template.php';
?>
it shows my background pic and the content; 'test'.
I think there is something wrong with my functions but i triple checked them
Sooooo help!
Here is the MenuController.php file;
<?php
require ("Model/MenuModel.php");
class MenuController {
function CreateMenuDropdownList(){
$menuModel = new MenuModel();
$result = "<form action = '' method = 'post' width = 200px'>
Type:
<select name = 'types' >
<option value = '%' >All</option>
".$this->CreateOptionValues($menuModel->GetMenuTypes()).
"</select>
<input type = 'submit' value = 'Search' />
</form>";
return $result;
}
function CreateOptionValues(array $types){
$result = "";
foreach ($types as $type){
$result = $result . "<option value='$type'>$type</option>";
}
return $result;
}
function CreateTypeTables($types){
$menuModel = new MenuModel();
$menuArray = $menuModel->GetItemsByType($types);
$result = "";
foreach ($menuArray as $key => $product){
$result = $result .
"
<table class = 'coffeeTable'>
<tr>
<th></th>
<th>Name: </th>
<td>$product->desc</td>
<tr>
<tr>
<th></th>
<th>Type: </th>
<td>$product->type</td>
<tr>
<tr>

<form method='post'>
