Not really sure how to go about this, and I think some of that is because of how I am interpreting the instructions, but I could use some direction for this challenge.
def repeat(string, times) fail "times must be 1 or more" if times < 1 counter = 0 loop do print repeat(string) counter + 1 if counter == times break end end end

A couple issues here.
First, you're actually making a call to the
repeat method from within the repeat method:
def repeat(string, times) # ... print repeat(string)
That's called "recursion", and it's probably not what you want to do. In this case, it's failing because
repeat is defined to take two parameters, but you're only passing one argument. But even if it worked, it would cause an infinite loop, as
repeat keeps calling itself. So don't call
repeat at all. Instead, you should just say:
Second issue is with this line:
counter + 1
That does add 1 to the value in counter, but then it doesn't do anything with it. For example, if I wrote:
counter = 0 counter + 1
counter would still be
0. Instead, you want to write
counter = counter + 1, or better yet
counter += 1. That will actually update the
I made the above changes to your code, and it worked for me. Give it another shot!
