Yes I just learned a little bit about functions a couple days ago in school.  I am completely new to programming so thanks for any help!

Ok I see.  

I changed it a little based on what you suggested and I got a change, the outline became red but the fill is still black.  Can you walk me through where I’m going wrong on what I have below?  

From what I gather, I have a function called fillcolor with a parameter called color.  I know this is going to sound stupid but I get a little lost after that.  The function says when ever I call fillcolor do what’s in the body?  What exactly does the parameter do (in this case color, how is that doing anything) and what is an argument?  

def fillcolor(color):    <- Function with parameter, right?
    pencolor(color)     <- Says make pencolor whatever I state when I call fill color, right?  	
    begin_fill()	      <- starts filling the star.  When I put color in () though I get an error that it takes no arguments?
    star(500)	      <- Star function 
    end_fill()	      <- Ends fill

red = "red"
fillcolor(red)


I know that I know absolutely nothing but I’m trying and I just started so please bare with me.  And thanks for any help, it's GREATLY appreciated!!

Scott
