How to a post new number to my spread sheet

I set it up but now don't know how to access it to post my latest entries. Guess I need some more step by step help! :lol:

 

You log into Google Drive.
Go through your list of files.
Double-click on your spreadsheet file.
It will open.
Scroll or arrow or page down to the row where you want to enter your data.
Enter your data.
Close the file; it automatically saves.
Close Google Docs.

Note: clicking on the link in your signature takes you to a read only version of the spreadsheet, not the one you can edit.
