The PHP MySQL query does not

I'm having some issues trying to insert a query into the database. I have this php form that should do an insert query but nothing happens, not even an error.

This is an example query with the form:

INSERT INTO FlashVideoList ('title', 'urltitle', 'description', 'tags', 'category', 'filename', 'filetype', 'size', 'uploadedbyuser', 'uploadtime') VALUES ('testtitle','testtitle','test','testtags','FlashVideo','SMILE!.swf','application/x-shockwave-flash','1007525','0','1339102426');

i echoed the contents of the query to get this

This is the php code:

function MySqlQuery($Query)
{
    // Invokes global connection info
    global $MySQL_Host, $MySQL_Username, $MySQL_Password, $MySQL_Database, $MySQL_Port;
    global $mysqli;

    // runs query
    $result = $mysqli->query($Query);
    return $result;
}

$mysqli = new mysqli($MySQL_Host, $MySQL_Username, $MySQL_Password, $MySQL_Database, $MySQL_Port);

    MySqlQuery("INSERT INTO FlashVideoList ('title', 'urltitle', 'description', 'tags', 'category', 'filename', 'filetype', 'size', 'uploadedbyuser', 'uploadtime') " .
    "VALUES ('" . $mysqli->real_escape_string($_SESSION['Title']) . "','" . $mysqli->real_escape_string(GetUrlTitle()) . "','" . $mysqli->real_escape_string($_SESSION['Description']) . "','" .
    $mysqli->real_escape_string($_SESSION['Tags']) . "','" . $_SESSION['Category'] . "','" . $mysqli->real_escape_string($FlashFileName) . "','" . $mysqli->real_escape_string($_FILES["file"]["type"]) . "','" .
    $mysqli->real_escape_string($_FILES["file"]["size"]) . "','" . $mysqli->real_escape_string($UploadUserID) . "','" . time() . "');");

mysqli_free_result($result);
mysqli_close($mysqli);

Any help is appereciated, thanks Select queries work fine with this same code

EDIT: Alright, i've made some progress, it seems that about everything possible is wrong with this code :P so yeah this is my query now:

INSERT INTO FlashVideoList (`title`, `urltitle`, `description`, `tags`, `category`, `filename`, `filetype`, `size`, `uploadedbyuser`, `uploadtime`) VALUES (`letitle`,`letitle`,``,`tagzz`,`FlashVideo`,`585336_pokemonsnewgrounds.swf`,`application/x-shockwave-flash`,`5058231`,`0`,`1339103842`);

And if I run it directly through navicat i get the error:

[Err] 1054 - Unknown column 'letitle' in 'field list'

Anyone know what i'm doing wrong? :/

Read the error message. What error message? Well, that's another issue, but it would have said why the insert failed1.

One (but perhaps not the only) problem as mentioned in the comments is that ' is not a valid identifier quote and thus results in a parse error. In MySQL the default is `, but it can be changed (to ") if using ANSI quotes.

INSERT INTO FlashVideoList (`title`, ...)

1 Here is an example of basic error handling for mysqli (scroll to the bottom). The basic idea is, if the query returns FALSE then something failed and error can/should be consulted.

Also, I'd recommend cleaning up the code and getting rid of the "proxy" function call.
