My front gears won't shift properly into third gear.
Is this a good question?

If your shifting used to be fine, your shifter cable may need to be tightened or perhaps the derailleur was knocked and rotated. Park Tools has published a pretty good guide on adjusting derailleurs, but your results may vary depending on the type and model of derailleur you have.

front derailleur usually has a 'over-shift' screw which keeps it from shifting too far and pulling your chain off the front casett. With riding this can rotate in/out.
