Hi ZhiSheng,
It would be very helpful to know the exact configuration that you have your counters connected in. By this I mean the exact pin numbers each line is connected to. This will help to verify that each counter is connected to the proper terminals and configured properly in the VI. A screen shot of the VI front panel will also help to confirm your configuration. Please post back with this information and we can take a look at some possibilities.
