We are encountering problems in the if statements in the program and cannot run it in the local host in the xampp.

PHP: 
if(isset($_POST['submit']))
    {
$kWh=$_POST['kWh'];

$offsetpercent = 0.0;
$offset = 0.0;
$offsetpercent = $offset / 100;
$offsetpercent = $offsetpercent + 1;
    
$size=$kWh / 30 / 4.5 * 1.15 * 1.2 * $offsetpercent;
   
echo '<br> This is the Solar Array Size in kW: </b>';

Don't know if it's related to your problem but, you set $kwh to $_POST['kwh'] then further down you set $kwh = true. Then you are comparing $kwh in various if and elseif statements. In essence you are saying if true < 300 do something.
