GROUP BY clause with Alias

Question

Hi,
I am trying to run following query and i tried to run littel different way but no luck.
If someone can help me out.
I know that icann't use the alias in GROUP BY clause.
I am getting errors like "NOT a GROUP BY Function" or Identifier is not valid within my different fromat of the sql.
For C_CODE (MAx function part_, i have to make a header for each C__CODE and put the corrospondence value for S_TASK.
SELECT  s_name ,login, f_name, l_name, email, S_ID, S_EMAIL,
desc, wave,
MAX(DECODE(C_CODE, '100',S_TASK, '')) "100",
MAX(DECODE(C_CODE, '150',S_TASK, '')) "150",
MAX(DECODE(C_CODE, '200',S_TASK, '')) "200"
FROM
SELECT  b.S_name, d.login, d.f_name,d.l_name, d.email,
*(SELECT d.login FROM user d WHERE d.id = c.rep_to_id) AS S_ID,*
*(SELECT d.email FROM user d WHERE d.id = c.rep_to_id) AS S_EMAIL,*
e.desc, f.wave, C_CODE, S_TASK
FROM CT_E_STAK_MAP       A,
ct_stak           B,
e_info           C,
user                D,
e_code           E,
e_web_info           F,
C_STAK_MAP           G,
C_CORS           H,
C_S_TASK           I,
C_S_STAK_MAP           J
WHERE a.C_stak_id      = b.c_stak_id
AND   b.c_stak_id      = G.c_stak_id
AND   B.C_STAK_ID      = J.C_STAK_ID
AND   J.C_S_TASK_ID      = I.C_S_TASK_ID
AND   G.C_CORS_ID           = H.C_CORS_ID
AND   a.U_id              = c.U_id
AND   a.U_id              = d.id
AND   d.id              = f.U_id
AND   c.ctll3           = e.c_st_val
AND   c.ctl1_2           = e.ctl1_2
AND   e.c_set_name      = 'EY'
AND   c.active          = 1
GROUP BY b.s_name, d.login, d.f_name,d.l_name, d.email,d.login, d.email, S_ID, S_EMAIL,
e.desc, f.wave, C_CODE, S_TASK
GROUP BY s_name ,login, f_name, l_name, email, S_ID, S_EMAIL, desc, wave
Please let me know if you need more info.
Thanks for your help!

<ul><li>Thanks for your help!
     I tried to import your query into my existing query but getting error.
     I love to post table/Insert script but i have lots of join tables and also using to retrieve data from those tables in my output results.
     If you see my original query then still you need crate table / Insert data script then please let me know.
     This is my original query:
<ul><li>SELECT  s_name ,login, f_name, l_name, email, S_ID, S_EMAIL,</li>
<li>desc, wave, </li>
<li>MAX(DECODE(C_CODE, '100',S_TASK, '')) "100",</li>
<li>MAX(DECODE(C_CODE, '150',S_TASK, '')) "150",</li>
