title: Cross Check Google Forms and Google Sheets
body: <p>So I am having a bit of a problem. I am currently making a google form sign up sheet. The only thing is I only want people to have the ability to sign up for certain things if they meet a certain criteria stated in our google sheets document. Currently, I have a spreadsheet email list, of everyone who has been approved. When filling out a google form I want it to block someone from signing up for a spot if they don't meet the approval criteria. Here is an example question.</p>

  <p>If the volunteer is not registered in our google sheets database to be a driver then I want the google forms to block them from choosing that option. I understand script for the most part, I am just unsure how to link the two together. Please let me know if this is possible. If it is, then any help you can provide would be greatly appreciated.</p>
