[SOLVED] double check my BMI calculator

[darkfreaks]

just want to make sure i programmed it right.  also  the action is going to be the thread number would it automatically carry out the action and post it in the thread number? or would i have to do something in order for it to post in that thread.

 

 

<?php 

$height= trim($_POST['height']);
$height=str_replace(',','.');
$weight=trim($_POST['weight']);
$height=str_replace(',','');
$height=str_replace('.','');



if ($_POST['height']||$_POST['weight']=="true") 
{ $heightwo=$height/2; 

$total=$weight/$heightwo *703;}

echo "your Mass Body Index is:"($total);

?>
