External table.How to load numbers (decimal and scientific notation format)

Question

Hi all, I need to load inside an external table records that contain 7 fields. The last field is called AMOUNT and it's represented in some records with the decimal format, in others records with the scientific notation format as, for example, below:
CY001_STATU;2009;Jan;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Jan;11200100;'60800;CYZ900;41380,77
The External table's script is the following:
CREATE TABLE HYP_DATA
COUNTRY VARCHAR2(50 BYTE),
YEAR VARCHAR2(20 BYTE),
PERIOD VARCHAR2(20 BYTE),
ACCOUNT VARCHAR2(50 BYTE),
DEPT VARCHAR2(20 BYTE),
ACTIVITY_LOC VARCHAR2(20 BYTE),
AMOUNT VARCHAR2(50 BYTE)
ORGANIZATION EXTERNAL
( TYPE ORACLE_LOADER
DEFAULT DIRECTORY HYP_DATA_DIR
ACCESS PARAMETERS
( RECORDS DELIMITED BY NEWLINE
BADFILE 'HYP_BAD_DIR':'HYP_LOAD.bad'
DISCARDFILE 'HYP_DISCARD_DIR':'HYP_LOAD.dsc'
LOGFILE 'HYP_LOG_DIR':'HYP_LOAD.log'
SKIP 0
FIELDS TERMINATED BY ";"
MISSING FIELD VALUES ARE NULL
REJECT ROWS WITH ALL NULL FIELDS
"COUNTRY" Char,
"YEAR" Char,
"PERIOD" Char,
"ACCOUNT" Char,
"DEPT" Char,
"ACTIVITY_LOC" Char,
"AMOUNT" Char
LOCATION (HYP_DATA_DIR:'Total.txt')
REJECT LIMIT UNLIMITED
NOPARALLEL
NOMONITORING;
If, for the field AMOUNT I use the datatype VARCHAR (as above), the table is loaded but I have some records rejected, and all these records contain the last field AMOUNT with the scientific notation as:
CY001_STATU;2009;Jan;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Feb;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Mar;11220020GR;'03900;CYZ900;-9,99999999839929e-03
CY001_STATU;2009;Dec;11220020GR;'03900;CYZ900;-9,99999999839929e-03
All the others records with a decimal AMOUNT are loaded correctly.
So, my problem is that I NEED to load all the records (with the decimal and the scientific notation format) together (without records rejected), but I don't know which datatype I have to use for the AMOUNT field....
Anybody has any idea ???
Any help would be appreciated
Thanks in advance

@OP,
What version of Oracle are you using?
Just cut'n'paste of you script and example woked FINE for me.
however my quation is... An external table will LOAD all data or none at all. How are you validating/concluding that...
I have some records rejected, and all these records contain the last field AMOUNT with the scientific notation
