After two hours of scanning both my 5D and my Speedlite manuals, I can't seem to toggle the mode button to ETTL (to enable "fully automatic flash shooting"). I have the program mode of my 5D set to "P". Pushing the mode button on the flash toggles the LCD panel from TTL to M and then to Multi and then back to TTL. As a result, I can't get the flash to work. Any ideas would be so much appreciated.
