Semicolons are used in two ways, to separate related independent clauses: "I entered the room; it stank." and as a kind of "super comma" when separating lists of items that themselves contain commas: spam; eggs and spam; spam, egg, sausage, and spam; and spam, spam, spam, eggs, and spam. The use here is the first case, and it's incorrect because (as another respondent has pointed out) the first clause is not independent (i.e. cannot stand on its own).
