Hi Folks,

I've been using "variable variables" for years with PHP.

$var = "myVarName";
$$var = "Some Val";

echo $myVarName; //outputs "Some Val"
[snip]
Example:

$var['first']='bob';
$var['second']='frank';

$varName = "myVarName";
$$varName = $var;

echo $$varName['second']; //should output "frank" but doesn't. :-\
<-----------------------------
echo $var['second']; //should output "frank" works fine.

Try adding

	$frank = 'woopsie!';

to the top of your script and running it.

-----

	echo ${$VarName}['second'];

is what you want - you want to be very clear what order these things 
need to be analyzed in, especially when dealing with arrays and the likes.

Cheers,
