If Player.GetEquippedSpell(1) == SummonGreaterMinion			Player.EquipSpell(SummonLesserMinion, 1)EndIf		Player.RemoveSpell(SummonGreaterMinion)

For some reason it doesn't swap the spells and it does NOT remove summongreaterminion.

What is the type of 'Player', friend?
With this new scripting language, I learn the hard way that you have to pay extra extra extra care with type & type casting. Even with dropdown box for ReferenceAlias. Once wrong cast and the script didnot work (even thou it complies)

I don't think casting would be the problem here, if the script compiles.

Have you tried putting a couple of debugging functions in there to make sure the code is running?

Do you have the Player property set up correctly?
