[1.7.2]Minecraft Crashing, Unsure why

[Delta 72 Knight]

I hate posting messages like this because I know they annoy me but I really can't figure this one out.

While coding to add a liquid today(Just one that looked like oil) I was having difficulties in getting one to work, I finally got to what I thought was the solution. Then it crashed and I can't figure out why, I can read the errors okay now thanks to my experience but I can't find out where this one leads, or where to fix it. Any help is appreciated!

 

Here is the Whole crash report

And if you want to look through my code here it is:

This is the main class

and this is the block class for the liquid

You need to add

myFluidInstance#setBlock(myBlockInstance)

after you've initialized your block and fluid.

So for me it would be like this?

fluidOil.setBlock(blockOil);

And it would go right in place where? I put it below my GameRegistry at the bottom of the PreInit Event and I still get the same error 

I have tried it in a few varied spots and have gotten the same or little difference in result.
