Question : Increasing a value in an access table

Very simple database for a voting procedure - Table "Candidates" with fields CandidateID, FName, LName, Position, and Votes. All fields are text except for votes (numeric)

on the form (based on the Candidates table) is just a combo box revealing the last names and another revealing the election position - I have a button on the form. I want the button, when clicked, to look at the LName in the combo box and increase the votes field for that record by 1. I am thinking a Dlookup - but I have not done it in some time and I would appreciate some help

Thank you
