Save an Excel file in the WEB
 

Hi there!
I uploaded an excel file into a WEB page and it starts when the page opens,
I can handle this file quite well, but when I try to save the changes this
option is not available or I have to make a long process to do it or I have
to type the link to open the file as a new window. I checked my permissions
with the administrator and everything is ok. How can I save easily this file
from web ?
thanks!
