Hi… i need help pls.
I have “Coins :” displayed on my GUI for coins that the player picks up during quests and it works perfectly for picking up the coin and adding 1 to the Global Variable and displays fine but the problem is that I cant subtract 
I use “Modify the text of a Text Object” to change the values and in the Value section in looks like this "Coins : " + GlobalVariableString(Coins) which adds one coin each time the player collects a coin but Im not allowed to enter “-” into the Value line…
How do I subtract 2 from the Global Variable and Display it?
Im doing a RPG Topdown style based game.
that’s just to edit the display of the value. To actually change the value I needed to edit the variable
