Hello, I have been following this topic for a while, and recently was able to install ML on my T4i(thank you very much to everyone here btw

) , and I have a couple questions that seem to still elude me.

1. I have noticed that people have been asking about advanced bracketing, is this feature currently disabled or unavailable?
2. I have been messing around with the scripts, mainly the custom exposure one, and i have edited it thusly:
// Custom bracket sequence
console_hide();set_aperture(22);
set_iso(100);
set_shutter(1./2000);
takepic();
set_shutter(1./1000);
takepic();
set_shutter(1./500);
takepic();
set_shutter(1./250);
takepic();
set_shutter(1./125);
takepic();
etc.....
but any time i run this script it just takes a few pictures at 1/125??? what am i doing wrong here
