Cannot resolve ORA-00955 error.

Question

I have a script which I run to drop and create preferences, set attributes and drop and create a context index. When dropping and creating preferences and setting the attributes everything works fine and I get the standard messages.
My problem is I get the
ORA-00955 name is already used by an existing object
even after seeing the messages "index dropped" and index created.
I have checked the ctx_user_index_errors view and the timestamps are from when I approximately ran my script so it seems the index worked.
I have tried prefacing the index name with the schema name both when dropping and creating the index and I have even tried to use the keyword "force" when trying to drop the index, yet I still get the ORA-00955 error.
A snippet from my code is below:
PROMPT 23 DROP oracle text context index
DROP INDEX schema1.my_index;
PROMPT 24 CREATE the oracle text context with the above preferences and attributes
CREATE INDEX schema1.my_index ON docs(doc_contents)
INDEXTYPE IS ctxsys.context
PARAMETERS('DATASTORE docs_data_store
FILTER CTXSYS.INSO_FILTER
FORMAT COLUMN oracle_text_format_column
LEXER docs_lexer
STOPLIST CTXSYS.DEFAULT_STOPLIST
SECTION GROUP docs_group
SYNC(ON COMMIT)' )
/

I think my problem was I really had a semi colon and a a foward slash at the end of the file, hence there was attempt to create the index twice, once for when the command was ended with a semicolon and once with the foward slash. I just removed the slash and everything worked fine.
