I am trying to use a click event to generate a popup window based off of the specific value chosen. I am having trouble with the if statement and trying to access each specific option value. Can any of you give me some hints?

        <select id="offices">
            <option value="Choose an Office">Choose an Office</option>
            <option value="Residential Education (ResEd)" >Residential Education (ResEd)</option>
            <option value="Dean of Students">Dean of Students</option>
            <option value="Office of Student Affairs">Office of Student Affairs</option>
            <option value="Vice-Provost of Student Affairs">Vice-Provost of Student Affairs</option>
        </select>
</div>

function display(){

        var officearray = [{
            Office: "Residential Education (ResEd)",
            ID: "725-2800",
            Description: "The Office of Residential Education is responsible for developing the policies, programs, and staffing which support the intellectual, educational, and community-building activities in student residences.  Second Floor. "

    }
    document.getElementsByTagName('option').addEventListener("click",display,false)
