[ic] Perl "space" question

[Grant]

How can I express something like this in a UserTag:

	$Scratch->{email} = $Scratch->{email}
$transaction->{Buyer}->{User}->{Email};

That's appending "$transaction->{Buyer}->{User}->{Email}" to the "email"
scratch variable after a space.  The way I have it above, IC restarts with
an error like this:

Scalar found where operator expected at (eval 79) line 42, near "}
$transaction"

        (Missing operator before  $transaction?)
