Hi! Ive this from gparis, but unfortunately, the programmer said, the code is not working/running

I have this, originally:
Code:
getURL("javascript:command('clue',1)","_self");
gparis taught me this:

Code:
ExternalInterface.call("clue(1)");
So should I change it to:

ExternalInterface.call("command(clue, 1)");


and how do I convert this: getURL("javascript:loadHistory(+1)","_self");


Help me please... thanks!
