Hi this is Bill and I'll be happy to help you. Your question is kind of too general. Can you post a link to the spreadsheet?
If I can access the spreadsheet I can probably just do the changes for you. Or if you prefer I'll tell you what needs to be changed.
No, I recommend to upload it to one of the many sites
wickisend is one of the most populars. Just go to wikisend.com and it becomes self explanatory
