kittra, you got to give it time. The normal pitching rate for most yeast is one 5 gram packet per 5 gallons. It will work with less...it just takes a bit longer (until they multiply). There is always a "lag time" up front for the first phase as the yeasties get comfortable and start to multiply. This normally would be in the period of 24-48hrs...although it's not uncommon depending upon conditions to see it go a bit longer. You won't see any big acitivty during this time. AFTER that, the yeast start to eat/work and you'll see foam on top, bubbles, activity.
If nothing happens after 48 hrs or so, (that's 2 days), then we can move on to other forms of trouble shooting to see what's going on. This iis all assuming of course that you have fermentable sugars in the fermenter to start with. (ie., what was your SG?). And also, understanding that cold temps could lengthen the time for everything to take place. But, it sounds like to me, you just haven't waited quite long enough yet.
