Combobox get() not returning selected value

[SnakesRule]

I'm trying to pass a name from a ComboBox to a MySQL search function, but no matter how I twist it, the get() always returns the first value in the combobox list, regardless of which name the user selects. Any ideas why?

ComboBox Window

import search

def match():
    #Initialize
    new2 = tk.Toplevel()
    new2.title("Matching Students and Projects")
    title = tk.Label(new2, text = "See Student/Project matches for:", font=("Arial", 12, "bold"))
    title.grid(row=0, column=0, sticky=W)

    #Create drop-down list of students
    students = ['student name', 'Student Name', 'Students Named']
    
    Pmw.initialise()
    studentmenu = Pmw.ComboBox(new2, label_text='Choose a Student:', labelpos = 'nw', scrolledlist_items=students, selectioncommand=None, entryfield_value=students[0])
    studentmenu.grid(row=1, column=0, sticky=W, padx=0, pady=5)
    
    #run the search
    close = tk.Button(new2,text="Match",command=search.search(studentmenu))
    close.grid(row=2, column=0)
    
    #Exit
    close = tk.Button(new2,text="Close Form",command=new2.destroy)
    close.grid(row=2, column=0, sticky=W)
    new2.mainloop()

Beginning of Search function

def search(menu):
    #Select the student
    searchname = menu.get()
    searchname = searchname.split()
    print searchname
    fname = searchname[0]
    lname = searchname[1]

I would think it should be...

searchname = menu.getSelecte d()

Just a thought.
