XLS upload via HSODBC. Unable to upload numeric (float) fields

Question

hi,
I wrote a program unit with Oracle Forms Builder 10g to upload and read an Excel sheet.
I created a HSODBC Data link to my DB, and used Excel 2003 to edit the XLS file to upload, and WEBUTIL_FILE_TRANSFER.CLIENT_TO_AS(client_dir_file,'\\server\dir\myfile.xls') to upload.
My DBLink works and Im able to upload the file. But it seems oracle is unable to upload some fields containing numeric (float) values.
running DESCRIBE Sheet1$@hsodbc; I got this table structure
UPLOAD_DATE          DATE
NUMBER VARCHAR2(32512 CHAR)
CODE VARCHAR2(32512 CHAR)
DESCR          VARCHAR2(32512 CHAR)
SIMILARS FLOAT(49)
WIDTH VARCHAR2(32512 CHAR)
HEIGHT VARCHAR2(32512 CHAR)
HIGH      VARCHAR2(32512 CHAR)
ITEMS      FLOAT(49)
fields SIMILARS, WIDTH, HEIGHT, HIGH, ITEMS contain numeric values in float format (ex: 1,00000). When I run
SELECT * FROM SHEET1$@HSODBC
I get that WIDTH, HEIGHT, HIGH columns are EMPTY (contain NULL values), while SIMILARS and ITEMS contains not null values.
I am sure that the \\server\dir\myfile.xls contains not null values for WIDTH, HEIGHT, HIGH fields! I tried to change cells format before upload, setting them to FLOAT, but I got no results!
Please help me, how can I do to change cell format in order to obtain a correct upload?

E.C.
there is a mistake in the subject. As I said in my thread, the upload works and the uploaded file contains all values. My problem is that I am "unable to READ" the numeric values stored in VARCHAR2 fields.
