Percent converted

Percent converted

I am having a problem with a percentage number (100%) being converted to (1%) when uploading from an access database into my zoho table using the upload tool.  The way I have this set up is that users update a xls spreadsheet, the xls is linked into an Access db, then with the upload tool I update the zoho table.  When I look at the data in Access it is formated correctly.   If I manually upload it from the xls it works fine. 
 
Please advise
