    First, let me please say what an EXCEPTIONAL tool JotForm is and THANK YOU!

    Please see this form:

    I have a drop down field on the form with a list of names. I am trying to figure out if there is a way to prevent:

    1) someone using someone else's name to submit a vote

    2) prevent duplicates - two votes on one name

    OR, is there a better way to do this than a drop down field?

    THANK you!
