$_POST[] help

I have a form page with action "page2.php" and Method POST. On the form I have an input named IDNum3 , type "text"
then I submit

On my page2.php I am trying to retrieve the value placed in IDNum3 with $ID = $_POST[IDNum3]; but it doesn't seem to work

What am I doing wrong?

how does it not seem to work?

When I submit, and it opens my page2.php

I show nothing.

all I have in my page2.php is

<?php
$IDNum3 = $_POST[IDNum3];
echo $IDNum3;
?>

I am also trying the method="GET"

and then use a $_REQUEST[`IDNum3']; but I don't see anything on the screen with this either

1 way to test:

<?php
echo $_GET['somevar'];
?>

Now run the script, say test.php, as
test.php?somevar=hello

see if "hello" is output.
it is also possible that you are using an old version of PHP that doesnt support $_* type of predefined variables.

Thanks laserlight,

That test helped me find my problem. I am new at PHP and I way typing ` instead of ' inside the $_GET[] command

Thanks again
