Can't figure out how to get 600EXII-RT and 320EX to cooperate

Hello,

 

I have a Canon EOS 6D, a ST-e3-RT speedlite transmitter, a 600EXII speedlite, and an old 320EX speedlite. The camera, transmitter, and 600EX work together just fine, but I cannot for the life of me figure out how to get the 320EX to fire. I only have one flash group, the transmitter is set to master, and the two flashes are set to slave. Please help? Thanks!

I don't believe that the 320EX has a radio receiver, only optical.

Okay, great! That means it should flash when it sees another flash go off, right? I haven't been able to get that to work either.

No it should not. It only fires when it sees a specially coded burst from an optical master.

Oh, well, that explains it. Bummer! Thanks.
