Sure enough the code wont work, it didnt for me too until i made some changes to it.
for startes i wasnt able to understand this line

for ($Counter=0; $Counter<$_POST['Number']; $Counter++)

a $_POST for wot? but then i assumed this page might be called from some other page n so did not ask for an explanation about it cos i was able to run it after some modifications. this is the code that run for me..

#code for dynamic.php
<HTML>
<HEAD></HEAD>
<BODY>
<FORM METHOD=GET ACTION="dynamic2.php">
<?php
//for ($Counter=0; $Counter<$_POST['Number']; $Counter++)
//{
   $Offset = $Counter+1;
   //echo $Offset;
   echo "<BR>Please enter the name of child number $Offset";
   echo "<INPUT NAME=Child[] TYPE=TEXT><BR>";
//}
if ($Counter==0) echo"Press the button to move on";
?>
<BR>
<BR>
<INPUT TYPE=SUBMIT name="test" >
</FORM>
</BODY>
</HTML>

#code for dynamic2.php (suggestion 1)
<html>
<body>
<?
foreach ($_GET['Child'] as $name) {
        print "$name<br>";
}
?>
</body>
</html>

# gives output 
<html>
<body>
Jerry<br></body>
</html>

#code u posted
<HTML>
<HEAD></HEAD>
<BODY>
<?
$counter=1;
   foreach ( $_GET["Child"] as $c ) {
echo "Child #". $counter++ ." is $c ";
   }
?>
<BR>
<BR>
</BODY>
</HTML>

# gives output 
<HTML>
<BODY>
Child #1 is Jerry <BR>
<BR>
</BODY>
</HTML>

the other way i tried out the script was to include a number... heres wot i did
#dynamic.php
<HTML>
<HEAD></HEAD>
<BODY>
<FORM METHOD=GET ACTION="dynamic2.php">
<?php
$Number = 3;
for ($Counter=0; $Counter<$Number; $Counter++)
{
   $Offset = $Counter+1;
   //echo $Offset;
   echo "<BR>Please enter the name of child number $Offset ";
   echo "<INPUT NAME=Child[] TYPE=TEXT><BR>";
}
if ($Counter==0) echo"Press the button to move on";
?>
<BR>
<BR>
<INPUT TYPE=SUBMIT name="test" >
</FORM>
</BODY>
</HTML>

#dynamic2.php
<HTML>
<HEAD></HEAD>
<BODY>
<?
$counter=1;
   foreach ( $_GET["Child"] as $c ) {
echo "Child #". $counter++ ." is $c <br> ";
   }
?>
<BR>
<BR>
</BODY>
</HTML>

# heres the 'view source' 
<HTML>
<HEAD></HEAD>
<BODY>
Child #1 is Tim <br> Child #2 is Tom <br> Child #3 is Tee <br> <BR>
<BR>
</BODY>
</HTML>

tried these ways, it sure works but the question is does it work in the way u want? for that u'd have to tell wot exactly u r expecting as outputs for what inputs. i am sorry, but ur objective isint clear to me.
