Ok I am working on a SIMPLE game where you feed a dog and walk it and stuff. There are two bars (one for health and the other for how clean the dog is) and I want the bars to change when you take it for a walk and stuff.

Simple so far...

I have a "pre-game" page where you pick your dog.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>

<body>
<form method="post" action="dog.php">
<select name="dognames">
  <option value="Goldy">Goldy</option>
</select>

<input type="submit" name="button" id="button" value="Submit" />
<input name="health" type="hidden" value="100" />
<input name="cleanness" type="hidden" value="100" />

</form>
</body>
</html>

Then the php page with all the code....

<?php

$name = "Golen";
$health = $_POST['health'];
$cleanness = $_POST['health'];
$words = "I love you";
$action = "walk";
$mood = "Happy";

if ($_POST['food'] == 'bone'){
$health = $health + 2;
$cleanness = $cleanness - 2;
}

?>

<title>Untitled Document</title>

<style>
#health{
width:100%;
border:#990000 solid 2px;
height:6px;
}
#healthbar{
background-color:#FF0000;
height:6px;
width:<?php echo $health; ?>%;
}




#cleanness{
width:100%;
border:#000066 solid 2px;
height:6px;
}
#cleanbar{
background-color:#0000FF;
height:6px;
width:<?php echo $cleanness; ?>%;
}


p{
padding:0px;
margin:0px;
}

</style>
</head>

<body>
<p><img src="dogpictures/dog images/basic_dog_<?php echo $action; ?>.GIF" alt="Your Device Can Not Support Images, Sorry"  /><br /></p>

<p>Health <?php echo $health; ?>%<div id="health"><div id="healthbar"></div></div></p>

<p>Cleanness: <?php echo $cleanness; ?>%<div id="cleanness"><div id="cleanbar"></div></div></p>


<p>Mood: <?php echo $mood; ?></p>

<p><?php echo $name; ?> says: "<?php echo $words; ?>"</p>

<br />

<form action="<?=$PHP_SELF?>" method="post">
<p>Action:<select name="food" size="1">
  <option value="walk">Take On walk</option>
  <option value="brush">Brush</option>
  <option value="pet">Pet</option>
  <option value="bath">Give Bath</option>
</select>
<input name="Submit" type="submit" value="Submit" />
</form>
</p>

<br />

<form action="<?=$PHP_SELF?>" method="post">
<p>Action:<select name="food" size="1">
  <option value="bone">Dog Bone</option>
  <option value="steak">Steak</option>
  <option value="water">Water</option>
  <option value="dogfood">Dog Food</option>
</select>
<input name="Submit" type="submit" value="Submit" />
</form>
</p>



</body>
</html>

I am jsut working $health and $cleanness right now. I want to press "bone" (from the dropdown menu) and have it bring up the health by 2 and the $cleanness down by 2.

The code where this should work is...

<?php 

if ($_POST['food'] == 'bone'){
$health = $health + 2;
$cleanness = $cleanness - 2;
}

?>

But of course it isn't working. Infact it seemes to lose it or something because the value of $health (which I can see through the echo) gose away after I feed my dog a bone.

I am new and have little idea what I am doing so any help would be GREAT!
