Also:
OnActivate<Player<IfVariable<Cash [>=] (Amouont of money needed, in this case lets say 100)
OnVariableTrue<Player<CenterPrint<You recieved a gun!
OnVariableTrue<Player<AddItem<Gun
OnVariabletrue<Player<ModVariable<Cash<[Subtract]<100
OnVarialbefalse<Client<CenterPrint<Not Enough Cash!
Then to add cash to a player, use ModVariable. e.g.
Input < Player < ModVariable < Cash < Add < 200
That would add 200 cash to the player when the input is activated.
