Importing prospects go into wrong fields

Importing prospects go into wrong fields

When importing prospects from excel spread sheet I check fields prior to import and they are lined up correctly, but when they are uploaded, they upload  in the wrong field  and other fields are missing completely.   
The name of the prospect becomes the website and the name is in title (sometimes) and email goes into website.  Industry and phone number are missing even though they are on the spreadsheet and on the import list to check placement.
