Star Wars Knights of the Old Republic II Tips

Why Can't I Cast Heal (Or Another Force Power)
One of the reasons that you may not be able to cast heal is that you may not have enough Force Points racked up to use it yet.

Although your bar may look full, look at the maximum FP possible. If it is less than the amount needed to cast that force power, then you will not cast it, no matter how full your force bar looks.
