Report Query w. Column Alias issue?

Question

I have this query:
SELECT
TXI_IS_PROJECTS.PROJECT_NAME,
TXI_IS_PROJECTS.PROJECT_DESC,
TXI_IS_PROJECTS.PROJECT_SIZE,
TXI_IS_PROJECTS.PROJECT_STATUS,
(select NLS_INITCAP(name_f || ' ' || name_l) name from TXI_PEOPLE where userid= TXI_IS_PROJECTS.PROJECT_OWNER),
TXI_IS_PROJECTS.SYSTEM_OWNER,
TXI_IS_PROJECTS.CREATE_DATE,
TXI_IS_PROJECTS.SPEC_REVIS,
TXI_DOCUMENTS.NAME
FROM TXI_IS_PROJECTS
INNER JOIN TXI_DOCUMENTS ON TXI_DOCUMENTS.PROJECT_ID = TXI_IS_PROJECTS.PROJECT_ID
INNER JOIN TXI_DOCUMENT_SIGNOFF ON TXI_DOCUMENT_SIGNOFF.DOC_ID = TXI_DOCUMENTS.ID
WHERE TXI_DOCUMENT_SIGNOFF.SIGN_OFF_ID = :P9_SIGN_OFF_ID;
The issue with this line:
(select NLS_INITCAP(name_f || ' ' || name_l) name from TXI_PEOPLE where userid= TXI_IS_PROJECTS.PROJECT_OWNER),
It's giving me this error:
query column #5 ((SELECTNLS_INITCAP(NAME_F||''||NAME_L)NAMEFROMTXI_PEOPLEWHEREUSERID=TXI_IS_PROJECTS.PROJECT_OWNER)) is invalid, use column alias
I've tried various ways and it's still not working.

SELECT
  TXI_IS_PROJECTS.PROJECT_NAME,
  TXI_IS_PROJECTS.PROJECT_DESC,
  TXI_IS_PROJECTS.PROJECT_SIZE,
  TXI_IS_PROJECTS.PROJECT_STATUS,
  (select NLS_INITCAP(name_f || ' ' || name_l) name
   from TXI_PEOPLE
   where userid= TXI_IS_PROJECTS.PROJECT_OWNER) as "My Column",
  TXI_IS_PROJECTS.SYSTEM_OWNER,
  TXI_IS_PROJECTS.CREATE_DATE,
  TXI_IS_PROJECTS.SPEC_REVIS,
  TXI_DOCUMENTS.NAME
FROM TXI_IS_PROJECTS
  INNER JOIN TXI_DOCUMENTS ON TXI_DOCUMENTS.PROJECT_ID = TXI_IS_PROJECTS.PROJECT_ID
  INNER JOIN TXI_DOCUMENT_SIGNOFF ON TXI_DOCUMENT_SIGNOFF.DOC_ID = TXI_DOCUMENTS.ID
WHERE TXI_DOCUMENT_SIGNOFF.SIGN_OFF_ID = :P9_SIGN_OFF_ID;<br>
as "My Column"<br><br>
I just recreated it and that worked.<br><br>
