Liu Zhiruo is still having a problem:
Hi Vasileios,
Thanks for your advise. It really work when I edit my code according to the pointer one given by you above.
However, when I want to perfect my code following your pointers two and five,the same error occured again! Even though I have tried many times, it still fails.

Part of my critical code is below:
