Cheat Engine Values

Hi,
When I add some table to cheat engine and add the process AVA.exe, the values keep changing. Like in guns add, you have to change the values to specific number, when I try that, the values keep changing and it just dont changes to the number I want!

I apriciate any help.

P.S: sorry for bad english :P

Some things (like health) are server side protected, a lot of things can't be changed by cheat engine

the Value Changes for your actions in CE
EX: If you click buy on Pike nade the value will change then go to another weapon you will see thee value changing
