Cheat Engine

[barbatrukko]

Hi,
I have used the old version of "Cheat Engine" in the past several times and I always managed to get what I wanted.
I'm trying the latest version on a game that "would seem" easy to edit but I can not find the address that contains the value.
In particular, the user starts with a certain amount of money (for example 150 $). I build a turret and my budget goes down to 100. And so on ....

In fact, I look for cells containing "150" (more than 10,000 memory locations always come out) then build the turret and make the new scan looking for the value 100 (or the values decreased) .... nothing to do.
Some idea?
