FileReference failing to download file

programming flash
1

Hi,

I am using this code to download a file from a server (podcast episode mp3) but I click the submit button and nothing happens. The text field shows “Downloading episode X” but nothing happens, no browse-to-save window pops up or anything. Here is my entire code, no external.

It simply uses AMFPHP to drawback results to see if the podcast episode exists. If it returns a 1, the fileReference download is triggered. I’m pretty sure the rest of the code is fine, its just the “localRef.download(requestF);” bit that seems to be doing nothing.

I think it has something to do with the submit_btn listener not listening properly. :stuck_out_tongue: Can anyone help?

Thanks.
