Darn.
Did the yeast in a bottle thing, with a tube going to a bell in the tank. Everything is air tight....
I used some yeast, a good amount mixed in with sugar already dissolved in warm water. The yeast was originally put into cold water, then eventually mixed the two. Added a little more cold water...
Nothing. Its been over a day. No bubbles. The sugar is setting at the bottom of the bottle, i shake it up but it re-sets down there...

You are supposed to disolve the yeast in warm water. Cold water keeps it from fermenting. You might try putting the bottle in a container of warm water, it may warm up enough to start. I'd probably dump it and start over.

So can I dissolve the sugar and yeast in the same warm water? Then dump it into the bottle, then add however much coldwater I need?
Also, Im using that hard sugar type... Am I suppose to be using that soft powdery sugar?

Just use all WARM water, not hot cause that will kill the yeast. I used to mix up the sugar first then add the yeast Make sure you have a good seal as well!!!

As the yeast warms up it will be fine. I've put bottles into the refrigerator and then taken them out weeks later and they woke up at room temp and behaved normally. Cold slows yeast, heat can kill it (above 110 I think)
I set the bottle on top of the light fixture to gently warm it. Or a sunny window.
More likely however, is either old yeast or leaks in the system. If you have submerged the bottle and are sure there are no leaks, and you don't see any tiny bubble sin the bottle, then I suspec the yeast as out of date, check the package.
In baking, you are told to "proof" the yeast, that is to add it to warm, not hot water, let it sit for 10 minutes or so to mix well on its own as it fals and rises and rehydrates, then add a pinch of sugar. This should foam slightly -- that proves the yeast is OK. If there is no foaming, the yeast is bad, toss it and start over.

Also the yeast should be stored in the fridge after opening as well,

When you mix your sugar/water (and gelatine, if you use it) be sure that the water is near boiling. That way you're sure that the sugar (and gelatine) disolves completely. If you have sugar at the bottom, it may not be mixed completely. I also agree with what has been said above.
