Without seeing them, no.
If you are using global variables, remove the global calls and pass those variables as arguments to each of your functions instead.

The global variables does not have significant role in the codes, but there are some variables that have the same identifiers.
The global variables should not have any role in your code! The problems you are seeing are exactly the reasons it is never a good idea to use them.
Functions have their own workspaces, so variables of the same names in different functions will not have any effect on each other, even if you name them as arguments. If you have them as global variables, you will get unpredictable results that are difficult — if not impossible — to debug, as you have discovered.
thank you so much, I removed the global variables and it works, I thought when sending a variable to both the functions I have to name such variable as global.
"I thought when sending a variable to both the functions I have to name such variable as global."
When passing variables as arguments (as you should be doing) you should not declare those variables as global.
