Error Binding Parameter 0

   This method generates an error I don't understand.

     def OnVarAdd(self, event):
     newVar = varDlg()
     result = newVar.ShowModal()
     if result == wx.ID_OK:
       if self.appData.dbFileName != ' ':
         self.appData.cur.execute("insert into variable (var_name, var_desc, \
                                                    policy_name, sub_policy_name) values \
                                                    (?,?,?,?)", \
                                  (varDlg().varName, varDlg().varDesc,\
                                  varDlg().polName, varDlg().subName))
       self.appData.con.commit()
     newVar.Destroy()

produces

   File "/data1/eikos/variablePage.py", line 238, in OnVarAdd
     (varDlg().varName, varDlg().varDesc,\
pysqlite2.dbapi2.InterfaceError: Error binding parameter 0 - probably
unsupported type.

   Which is parameter 0? What syntax error have I committed here?

TIA,

Rich
