For example, when I want to lose a single price, the following amount is not Out of the result (each worksheet is like this), sometimes it is a day after a day, sometimes it is good, I will re-come back from the beginning. This is the reason for the software or my operation or computer system. What about the problem? I am going to count the salary. Ask, in the heart of God's sister, I know the reason, I will tell me immediately, I am frightened, I am so disappointment, thank you first.
