PHP无法在SQL中使用订单，但它在[关闭]之前有效

After adding this line 'order by Fines($)', it always said: Problem Query. when I delete die(problem query)function, it said cannot find the parameters.

<?php

if(isset($_POST["searchBtn"]))
{
    $strInputSuburb = "";
    $strInputStreet = "";

    $strInputSuburb = $_POST["suburb"];
    $strInputStreet = $_POST["street"];

    if(!empty($strInputSuburb) || !empty($strInputStreet))
    {
        $conn = @mysqli_connect("localhost", "example", "exmaple")
        or die ("Failed to connect server");
        @mysqli_select_db($conn, "example")
        or die ("Database not available");

        $querySql1 = "select * from Infringement 
                      where suburb like '%$strInputSuburb%' and street1 like '%$strInputStreet%'
                      order by Fines($) acs";***// After adding this line, it always said: Problem Query***

        $result1 = mysqli_query($conn, $querySql1)
            or die ("Problem Query...");.***// when I delete die function, it said cannot find the parameters.***
        $count = mysqli_num_rows($result1);
        if(!count==0){
            echo "<div class='table-responsive row' id='tableTop'>";
            echo "<div class='col-md-10 col-md-offset-1'>";
            echo "<table class='table table-bordered table-hover '>";
            echo "<tr><th>Location</th><th>Suburb</th><th>No. of Infringements</th><th>Fines($)</th></tr>";
            while($Row = mysqli_fetch_row($result1)){
                echo "<tr><td>Intersection of ".$Row[1]." and ".$Row[2]."</td><td>".$Row[3]."</td><td>".$Row[4]."</td><td>".$Row[5]."</td></tr>";
            }
            echo "</table>";
            echo "</div>";
            echo "</div>";
        }
        else {
            echo "No data found! Please search again!";
        }
        mysqli_free_result($result1);
        mysqli_close($conn);
    }
    else {
        echo "<div style='padding-top:9px;color:grey' class='col-md-3 col-md-offset-2'>";
        echo "Please type any <b>Suburb</b> or <b>Street</b>.";
        echo "</div>";
    }   

}
?> 

fix the: 'order by Fines($) acs' to 'order by Fines ASC'

and here is the code part (copy-paste it to needed line):

$querySql1 = "select * from Infringement where 
             suburb like '%".mysqli_real_escape_string($conn, $strInputSuburb)."%' and 
             street1 like '%".mysqli_real_escape_string($conn, $strInputStreet)."%'
             order by Fines ASC";

$result1 = mysqli_query($conn, $querySql1) or die ("Problem Query...");
if(mysqli_num_rows($result1)>0){
