Suggestion: put your code between <pre></pre> tags to make it readable. Hint: use the code block button in the editor. Question: what is your problem?

Well you have not specified any size for the array you are trying to create.

1. Inside the [] at the end, specify a length for the array. 2. You left off the semicolon at the end of the line.
