Problemer med PHP og MSSQL

Hej

Jeg har lidt problemer med en INSERT statement i MS SQL.. nogen der kan fortælle mig fejlen?

        $do = "INSERT INTO user_table([id], [user], [fullname], [email], [accesslevel], [dateAdded], [modifiedDate], [addedByUser], [password]) values ('', '".$_POST['txtUser']."', '".$_POST['txtName']."', '".$_POST['txtEmail']."', '".$_POST['selectAccess']."', '".Date("Y-m-d")."', '".Date("Y-m-d")."', '".$_SESSION['UserName']."', '".sha1("123456")."')";
        if (mssql_query($do)) {
            echo "<center><font color=\"green\">The user \"".$_POST['txtUser']."\" was created successfully.</font></center>";
            exit;
        }
        else {
            echo "<center><font color=\"red\">It was not possible to create the user \"".$_POST['txtUser']."\" at this time due to an error. Please contact xxx@xxx.dk</font></center>";
            exit;
        }
