A "while" needs a conditional expression between the parentheses, and the one here has nothing but a space there.

To make it work correctly, you need a comparison using "counter" that will be true until the loop body has run 10 times.

Thank you for responding. So what would the counter comparison be?

A typical expression would be "counter < some_value" — I'll leave it up to you to figure out what "some_value" should be to make the loop run 10 times. :wink:
