Right now I'm working on a PHP project where the user enters the lower limit and upper limit and the program will generate 5 numbers between that limit, print it out the randomly generated 5 numbers, and find and print the sum. For some reason my program isn't getting passed the input (lower and upper limits). Any help is appreciated, thanks all!

<body>
<h1>Find the sum of five digits!</h1>
<p>Enter in the lower and upper limits of the numbers you would like to
generate. Press "Calculate" to calculate the sum of the genreated numbers!
</p>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
Enter the lower limit: <input type = "number" name = "lowLim">
Enter the upper limit: <input type = "number" name = "upLim">
<input type = "submit">
</form>
<?php
if($SERVER["REQUEST_METHOD"] == "POST"){
$lowerLim = test_input($_POST["lowLim"]);
$upperLim = test_input($_POST["upLim"]);
$randomArray = array();
$sumArray = array();
$total = 0;
$arrCounter = 0;
var_dump ($lowerLim);
for($i = 0; $i < 5; $i++){
$randomRange = rand("$lowerLim","$upperLim");
$randomArray = array($randomRange[i]);
}
$sumArray = array($randomArray);
$total = array_sum($sumArray);
}
function test_input($data){
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
echo "First number generated: ".$randomArray[0];
echo "Second number generated: ".$randomArray[1];
echo "Third number generated: ".$randomArray[2];
echo "Fourth number generated: ".$randomArray[3];
echo "Fifth number generated: ".$randomArray[4];
echo "The sum of the generated digits is:".$total;
?>
