No value when setting variables based on $_POST variable.

[gsherp]

I have a html page with a drop menu
select name=color
(....a list of colors)
I select the color to be blue.

in my php code I have[code=php]
<?php
$color = $_POST["color"]; //$color = blue from form
if($color=="blu e") $amount=100;
if($color=="gre en") $amount=90;

$total = $amount * 2;

echo $total;
?>[/code]

I get no value for total.

If I initialize $value=3; before the if statement:
[code=php]
<?php
$color = $_POST["color"]; //$color = blue from form
$value=3;
if($color=="blu e") $amount=100;
if($color=="gre en") $amount=90;

$total = $amount * 2;

echo $total;
?>[/code]

I get a value for total to be 6.


PLEASE HELP

make sure ur $color variable have right value,
because i think nothing error here

[PHP]
<?php
$color = $_POST["color"]; //$color = blue from form
print "color is : $color"; //just to make sure $color value
print_r($_POST) ; //just to make sure $_POST value
if($color=="blu e") $amount=100;
if($color=="gre en") $amount=90;

$total = $amount * 2;

echo $total;
?>
[/PHP]

Heya, gsherp. Welcome to TSDN!

Is your form using POST or GET to send its values?

Try using $_REQUEST instead of $_POST.

it works now, but only after i type into another file and then cut and paste back into the original file....weird. AND i know i didn't mistype.
