Thats my whole ruby code from a tutorial

Anthony,

def mtf(arg1="Dibya", arg2="Shashank", arg3="shashank")

You miss-typed here: should be "mtd".

"#{arg1}, #{arg2}, #{arg3}."
end
puts mtd
puts mtd("ruby")

Haha, thank you!

The error is telling you that. You asked it to call the method mtd, it says
"undefined local variable or method 'mtd'" but you know it exists right
there, since you just wrote it. So you should be asking yourself why it
can't find the method that you can see. Misspelled names are the most common
cause of this. Second most common is probably accidentally defining an
instance method instead of a class method.

Try to pay attention when things like this happen. See what it says, think
about why it says that and what could be the causes. Take note of the
solution. After a while, this will help you develop an intuition for
resolving issues like this.
