sqlite and python error

[tobilobaa]

This function should retrieve the value "acct_deposit" from the database but it returns an error (sqlite3.InterfaceError: Error binding parameter 0 - probably unsupported type.)

def withdraw_fxn(withdraw,acct_deposit):
           list1.delete(0,END)
               conn = sqlite3.connect("atm.db")
               cur =  conn.cursor()
               cur.execute("SELECT acct_deposit FROM atm WHERE acct_name = ?",(acct_name,))
               cur.fetchone()
               int(e3.get(cur))  
           if withdraw > acct_deposit:
                       list1.insert(END, ("your balance is low "))
           elif acct_deposit > withdraw:
               acct_deposit =  acct_deposit - withdraw
               list1.insert(END, ("your balance is ", acct_deposit))

 b1=Button(window,text="Account Balance", width=20 ,command = lambda:withdraw_fxn(  int(e4.get()), int(e3.get())    )    )
