ok well there are some things i’d change, like your error checking is really very lackluster. for example, after your form you look for the $_POSTed info, but what if you haven’t filled the form out yet? errors! I duplicated your if isset so that it would not process the unneeded code. better yet, you could make it check for the individual results before trying to echo their table row, etc. i did a fast copy paste:
[php]<?php if (isset($_POST['investment'])) { ?>[/php]
that being said, what do you WANT to happen with the monthly? you accept it as a form element but do nothing with it in your math. what should the math be on this?
MY assumption? you want to multiply the monthly deposit by 12, and then the number of years, and then you want to add it to the initial deposit before doing all of the math on it.
so here:
[php]<?php
if (isset($_POST[‘investment’])) {
$inv = ($_POST[‘investment’] + (($_POST[‘monthly’] * 12) * $_POST[‘years’]));
$int = $_POST[‘interest’]/100;
$yrs = $_POST[‘years’];
$message = "Please enter details as required!";
if ($inv=="") { echo $message; }
elseif ($int=="") { echo $message; }
elseif ($yrs=="") { echo $message; }
else {
$interestearned = $inv*(pow(1+$int,$yrs)-1);
$dailyi = $interestearned/$yrs/365;
$weeklyi = $interestearned/$yrs/52;
$monthlyi = $interestearned/$yrs/12;
$yearlyi = $interestearned/$yrs;
};
};
if(isset($_POST[‘monthly’])) {
$dep = $_POST['monthly'];
if($dep == 1){
$interestearned + (10 *($yrs *12));
}elseif($dep == 2){
$interestearned + (20 *($yrs *12));
}elseif($dep == 3){
$interestearned + (30 *($yrs *12));
}elseif($dep == 4){
$interestearned + (40 *($yrs *12));
}elseif($dep == 5){
$interestearned + (50 *($yrs *12));
};
};
?>
