Bracket not expected in else statement?

I have an error, unexpected brackets on an else statement, which makes no sense. What am I doing wrong?

if ($sortBy == "random") {
$sortByOption1 = "selected";
} 
else if ($sortBy == "mostvotes") {
$sortByOption2 = "selected";
} 
else ($sortBy == "newest") {
$sortByOption3 = "selected";
} 

Error:

syntax error, unexpected '{' on line 9
