This is a great piece of code and really will help me use powercards more in my game. I am having one issue though that I can't seem to figure out. The PC Attack does not work for me. I have given A PC attacks, completing all empty forms in the attack. I ran the !PCM script on the character, and when i push PC attack i receive the following error . I figure this is on me, as I have never gotten my head around the programming for Roll20, what am i missing? , PowerCards: "Could not determine result type of: [{\"type\":\"M\",\"expr\":0},{\"type\":\"C\",\"text\":\"d20$ + 4 [Attack Bonus] \"}]"
