IF (SELECT....) END IF; syntax issues

Question

I have that quite staight forward piece of sql here:
IF
(SELECT COUNT(DISTINCT FLOOR(CAST(x1 as float))) FROM SOURCEArchive) > 20 THEN
     DELETE SOURCEArchive
END IF
now the error is:
PLS-00103: Encountered the symbol ")" when expecting one of the following: . , @ ; for <an identifier> <a double-quoted delimited-identifier> group having intersect minus order partition start subpartition union where connect SAMPLE_
What am I doing wrong here. Is it invalid to have a select after the IF...?
when I do
IF
222 > 20 THEN
SELECT AData FROM SOURCEEArchive      
END IF;
I get PL/SQL: ORA-00933: SQL command not properly ended

------------------------------------------------------------Try:
declare
  v_cnt NUMBER;
begin
  SELECT COUNT(DISTINCT FLOOR(CAST(x1 as float))) INTO v_cnt FROM SOURCEArchive;
  IF v_cnt > 20 THEN
    DELETE FROM SourceArchive;
  END IF;
end;
