This is a tileset borrowed from Reiners Tilesets, and I will use it as an example..

The width and height of the tileset are 96 x 96. There are 3 x 3 tiles in this tileset... 3 rows and 3 columns. This means each tile is 32 pixels by 32 pixels..

This means you should set the tile width and height to 32 x 32..

Now, for horizontal offset and vertical offset, this is just for fancy tilesets. This is used when the top-left tile isnt in the very top-left corner, but is some distance away. You use the offsets to position the little green boxes over the first tile, and then you use the H and V seperations..

H sep and V sep are the distance in between tiles. In the example above, each tile is packed up very close, with no spaces in between, the other tiles. This means both of these values need to be 0. But, say each tile had a 1 pixel thin border, then you now need 1 H sep and 1 V sep, to seperate the tiles a small amount.

Play around, it's the best way to learn.

Thanks guys! I got it perfectly!!!!!!!!!

Make sure you have the box that says "Use as tile set" checked. Also, change the tile width and tile height to what they should be. I'm guessing those numbers may be too large, so it is acting as one big tile.

Thanks! That fixed it! But now these thin little green lines are surrounding my tiles how do I fix this? The tiles hight and width is 17X17. I have horizontal offset and vertical offset on 0. And same for H and V sep. Is that my problem?

Ok so 3 months is a little bit exaggerated.  But maxing games at 450 bucks!? No way! The minimum laptop at dell is 500$ and I can tell you right now that it can't play a lot of games. Don't get me wrong it can play I'd say like 50 or 60% (maybe) of games for PC, but that means that your computer for 450$ can play 90% (unless you were implying it can play ALL games.)
If people could go out and buy a PC that was powerful enough to run just about any game for 450$ then there would be no need to buy a playstation 3 or xbox 360.

But maybe you know some super secret place to buy gaming PC's, in that case PLEASE TELL. Or...you meant 4500$.

Two words.
Custom building.
Most people don't do it because they think it would be too hard putting a pc together, and really, the hardest part is making sure all of your parts fit together.  Most of the stuff in your computer really just "plugs" into other parts, there's not much hard about it.

Wow...I never thought of that! Cool! I'll look into it. Thanks.  

I think computers playing games is totally awesome but in order to keep it up to date you have to buy new (expensive) parts for it every 3 months. It's just not worth it. Do you have to do that with a gaming machine? No.

Do I have to buy new (expensive) parts for my PC every 3 months?  No.
Last time I checked, all the hardware except for my core 2 duo has been available for about 3+years, and I'm still maxing games.
Nowdays my computer would only cost like $450, too, the power supply would cost the most.

EDIT x2: Sonic 3 and Knuckles was the greatest Sonic. No exceptions. *braces for flames*

I have a very special place in my heart for sonic 3 and knuckles, but I must disagree.  Sonic 2 was the best.
