How does the PHP know what those objects are? Is your javascript is on a separate page from the rest of the PHP that created the objects?

nope all my code is in one form.php 🙂

I take it that it works as expected when you echo out the objects inside the PHP?

[helloise]

the alert comes up and that is about it. if i echo anything else(ex: echo "testing") inside the php that also does not come up... 🙁

Odd, echo"testing"; should work. My only suggestion is maybe it doesn't like the <?PHP in capitals, I always use lowercase. Sorry I can't be much more help.

Look at the source code of the page - I think you'll find that those echo statements are working.

All PHP code is executed before the page is even sent to the user's browser. You can't execute PHP from within Javascript since PHP is a server-side language (meaning it is parsed and executed by the server before sending its output to the client) while Javascript is a client-side language.
