Apr 17, 2008 12:34pm dob Scriptwright	Hey there, let's say I have this code: `<body> <script>var foo = "bar";</script> <frameset> <frame src="page.html" /> </frameset> </body>` Inside `page.html`, I got a function which alerts the variable `foo` It doesn't work, so I'm asking: Is there a way to read variables inside an iframe page which are embedded inside the page embedding my frame page? Thanks!
