I''m using FF2 + prototype 1.5.1
this small line is giving me a problem: $$("#splash-
description .buy").hide();
Firebug says this:
$$("#splash-description .buy").hide is not a function
if I use a single $ the the hide() function seems to work...
why is this function now working for the double $$?

from the quick looking i just did i think you want to do something along the
lines of
$$("#splash-description .buy").invoke(''hide'');
or maybe
$$("#splash-description .buy").each(Element.hide)
because the $$:
Takes an arbitrary number of CSS selectors (strings) and returns a
document-order array of extended DOM elements that match any of them.
thus you need to iterate through all of them even if there is only one to
iterate through.
i could be completely out in left field on this, so i look forward to
someone confirming this one way or the other.
