	if (isset($_POST['BMEC'])){
	$tot = 0;   // clear vairable
	$BMTot = 0;   // clear vairable
    $tot = $tot + ($_POST['BMEC']);   //gets value from user input
	$BMTot = $tot;   //Assign value to variable

    $tot = $tot + ($_POST['BME']);
    $tot = $tot + ($_POST['BMNE']);
    $sectionBMT_result = $tot; 
	$sectionBMT2_result = $BMTot;	// NOW here is the problem if you echo this if gives me a result of two which is correct cause my input was 1. the problem lies when i display result in another text box it does not show ???
	echo $$sectionBMT2_result; } ?>">

       ?>

<input name="BMEC2" type="text" id="BMEC2" size="6" value="<?PHP if ($sectionBMT2_result){ // this field is not in my code here

your code could be greatly simplified:

if (isset($_POST['BMEC']))
{
	$array = array(
	$_POST['BMCEO'],
	$_POST['BMCOO'],
	$_POST['BMCFO'],
	$_POST['BME'],
	$_POST['BMNE']
	);

$total = ($_POST['BMEC'] * 2) + array_sum($array);

echo $total;
}
