but i want it so that if it goes up or down it changes, so it would have to be like, gold becomes not equal to what it currently is? how would i do that? i dont see any option like that either..
Sure there is. ;)
Let me open the editor and create an example for you.
The right picture shows how to make the player get more gold.
You have to make it an Arithmetic function, then change the first reddened out value to "Player - Property", and the second value to whatever number of gold/wood you want to add.
Or, if you just want it to set it to a specific number, you can do what the left picture shows.
