Help with an ability that costs gold/lumber...

[Ordonian]

How exactly do I do this?! Im making an RPG where you level up and get lumber and choose which of the three attributes you want to increase, each costing 1 lumber to increase. Right now Im using a spell book with three different abilities, but with my limited knowledge of triggers, I can't seem to find a way to make this work. So how do I make these abilities cost lumber to use?

    • Lumber of owner of triggering unit greater than 0
  • Actions:

• Add 1 strength or agility or intelligence to triggering unit
