That's the first of a few issues you'll need to fix. Here's some hints:

  • you declared loop inside the while loop, but you need to declare it before the while loop.
  • you forgot to end the line declaring loop with a semicolon (";")
  • you won't need to call ReadLine again
  • you still need to print "Yay!" inside the loop

Declaration and initialization should only happen one time. If you put it inside the loop, it will happen over and over.

Also, if you have not already declared it before the while statement references it, it will cause a compiler error.

Even more important, if you set the value to 0 inside the loop, then increment it to 1, it will always be smaller than the times value, and the loop will never end.
