Do you see the extra right parenthese on this line?

    digitalWrite(ledPins[thisPin]), LOW);

By the way, putting the error message by hand into the title is a bad way to go. It leaves out valuable information and causes some things to be spelled incorrectly. In the future, error messages should be copied and pasted between code tags.

By the same token, copying code by hand from a tutorial is going to create errors that you cannot easily find.
