Need help syncing two comp. with live...i tried searching!

[aus9]

so im playing this friday, and will have another computer synced to mine. ive never had to try to sync two computers together, so it is new to me. i searched, and found that one of the steps in this process involves clicking the 'EXT' button on the slave computer. well, i cant find the damn ext button! does live 7 have a different location for it than previous versions? i googled screenshots of live and found it near the tempo but it is not there on mine.

The EXT button only appears if you turn on "sync" for a particular midi device in preferences. (this is in the manual)

so you're going to play this friday with a configuration you've yet to even get working...well i'd definitely give you 10/10 for courage!
