Getting a textbox set to a vairable

[mlsbraves]

This use to work on a online host of mine but it won't work now:

input.php

<form name="getinput" method="post" action="result.php">
Input: <input type="text" name="value"><br>
<input type="submit" value="Update Data">
    </form> 

result.php
<? echo ($value); ?>

I just get a "Notice: Undefined variable: value"

I've searched and don't know why I havn't been able to find a simple script.

it meens that global variables are turned off.

try

echo $_POST['value'];

Thanks, that worked for everything except one part of my code. I'm retreiving the contents of a page and the vairable is part of the page name.

$subject = file_get_contents('http://<? echo $_POST['vairable']; ?>.com/index.html');

I get "Parse error: parse error, unexpected T_STRING"

'echo' outputs to the browser. you dont want to output in this case, you just want to use the value.

$subject = file_get_contents('http://' . $_POST['vairable'] . '.com/index.html');
