I don’t understand, there are quotation marks and some without quotation marks, please write the program according to the rules, and then read it
===================================
The masters are all the same (read the second tone, the same).
At that time, I changed the website for a company. The program was changed using a Korean forum. The source code was messy. I also took it out of context. The work progressed very slowly. I didn't get a complete solution to this problem. Later, I deleted the last added record and got it done.
I have tried some of the above methods, but I have not tried all of them. Thank you for your answers. I must study the problem carefully
