CSV file upload problem
 

I don't know if this can be addressed in this group so apologies if I am wrong but I
cannot get my head round this one. A csv file is downloaded from the web for entries and
changes to be made which involves VBA procedures but with the exception of some data
validation being used there is nothing really that should "corrupt" the file.
If it is then saved and upload to the web then attempted a java error meaasge appears.
However if I was to save the file after adjusting it, then close it, then open it again
and save it again it uploads everytime without fail. It would be nice just to save it once
but so far all attempts have failed. Any thoughts on potential causes and solutions would
be very welcome.
