Google Forms has made many updates over the years. This post from 2013 is mostly outdated. Check out some of my other posts on Google Forms!
There are many things I am excited about in relation to the new Google Forms. However, it has added a layer of complexity by making the spreadsheet of data separate from the form itself.
I just created a sample Form in my delete folder*, but the response destination spreadsheet was created in My Drive. So the form and the connected spreadsheet do not live in the same folder.
*My delete folder is just a folder I created so that I can make sample documents when I do trainings or presentations.
First when you make a Google Form you will want to choose a response destination which is an option in the grey bar right above the Google Form.
What gets confusing is you are looking at the spreadsheet but want to view the form. However, since you are logged in you see the editing view of the form and not the live view. So you will want to be familiar with how to jump from one to the other.
My workflow is then to open either the form or the spreadsheet, no sense in digging around Google Drive to find the view I am looking for and then to use the navigation within there to get to the view that I am desiring.
