You have the wrong punctuation.

In the for statement, you separated the clauses with commas, but they should be separated with semicolons.

And for the line numbers to be useful in your code, you must format it using the instructions in the Markdown Cheatsheet found below the "Add an Answer" area. :arrow_heading_down:

When you combine strings, make sure you have the concatenation operator ("+") between each item being combined. Also make sure you only combine strings on the right side of an assignment.
