Getting Group Function is not Allowed

Question

Hello All....
When I run the following in the SQL command screen it works fine... But when I try to use it in APEX to populate page values, it gives me the error...
ERROR
1 error has occurred
ORA-06550: line 25, column 74: PL/SQL: ORA-00934: group function is not allowed here ORA-06550: line 24, column 1: PL/SQL: SQL Statement ignored
CODE THAT WORKS IN SQL COMMAND SCREEN
SELECT
SUM(CASE WHEN SLOT = 'Q' THEN '1' ELSE '0' END) AS C_SLOT,
SUM(CASE WHEN TEST = 'P' THEN '1' ELSE '0' END) AS C_TEST,
FROM TBL_REC;
CODE THAT GIVES ERROR ON APPLICATION EXPRESS PAGE
SELECT
SUM(CASE WHEN SLOT = 'Q' THEN '1' ELSE '0' END) INTO :P2_C_SLOT,
SUM(CASE WHEN TEST = 'P' THEN '1' ELSE '0' END) INTO :P2_C_TEST,
FROM TBL_REC;
The colums SLOT and TEST have letter codes, I just want it to count just when it matches a certain letter. In the SQL Command Screen, it is returning one row, with the counts, everything is fine. It is only a problem when I try to use it anywere on a page in Application Express.
The full version has about 20 lines that are all sum lines, but I can not even get the 2 line ver above to work.
Any thoughts?

This will work .. the into clause goes after the select columns ... into var1 ,var2 etc ..
SELECT SUM(CASE
             WHEN SLOT = 'Q' THEN
              '1'
             ELSE
              '0'
           END),
       SUM(CASE
             WHEN TEST = 'P' THEN
              '1'
             ELSE
              '0'
           END)
  INTO :P2_C_SLOT, :P2_C_TEST,
  FROM TBL_REC;SS
