How can I limit the people using my spreadsheet to the list of client names listed? My list works great, but instead of selecting Gino's from the drop down list, they type in "Ginos." I've search Data Validation and see the Warning message options, but not a limit to list option.

Also, I know if I have "Gino's" in the column cell once, then the next time someone types "G" in a cell that "Gino's" will pop up. Is there a way to have this happen the first time some types a "G?"
