Yeah tell me about it!  It's super fast and I feel like I'm falling 
behind.  Just need to study more!

Ok cool, this helped a lot!

One more quick question.  My function call is...

int maxValue = max3(a,b,c);

right?

I kinda just added maxValue because nothing was working and I seen a few 
methods being called with an entirely different (variable I guess). 
However, I just reran it without the maxValue part and it ran just fine. 
  Why would you want to create a new what I'm assuming is a variable to 
call your function?

Thanks everyone for all your help!  Not sure what I'd do without you 
guys and gals!
