sandbox violation

[bunglebrown]

I have a php page referenced to send an email from a flash movie (using actionscript 3.0). But for some reason that I cannot find when submitting the details the following message pops up:

Error #2044: Unhandled securityError:. text=Error #2048: Security sandbox violation: http://my_website/flash_doc.swf cannot load data from my_doc.php.
at flash_doc_fla::MainTimeline/flash_doc_fla::frame179()

Anyway to beat this and get this working as it should be?

_thanks all
