It compiles fine, but in game, when the script is called, it says that root is not initialized. Isn't that what I did when I declared it and then set it with this? "set root = GroupPickRandomUnit(roots)"

the problem lies at local integer id = GetUnitTypeId(root)

So before setting roots = a group and root = a random unit of the group, you set id = GetUnitTypeId(unitinitalised root)

Problem solved.

I hate how often I miss these little, obvious errors. Sometimes you just need someone who didn't write it to look at it and see what you miss because you know what you meant. like in an essay. Thanks.
