Copy a report from one folder to another

[WhiZa]

I am using Crystal Enterprise attempting to copy a report from one web folder to another via the API. I've tried using the Copy Method but with no luck. Has anyone done this before? Here's my attempt:
function moveReport (IStore, source, destination)
{
var Reports = IStore.Query("SELECT * FROM CI_INFOOBJECTS WHERE SI_NAME = '" + source + "'");
var Report = Reports.Item (1);

var Folders = IStore.Query("SELECT * FROM CI_INFOOBJECTS WHERE SI_NAME = '" + destination + "'");
var Folder = Folders.Item (1);

Folder.Copy(Report,2);
}

It gives me the error "Object doesn't support this property or method", but the Copy method is part of InfoObject (which is what the object Folder is). Any ideas?
