Could anyone figure out what is wrong with this???
Also, I have the current mods loaded: AdditionalPipes, AppliedEnergistics, Buildcraft, CoFHCore, Fairylights, Flans Mod, ThermalExpansion, ThermalFoundation, WorldEdit. Please also tell me if any of these are causing the errors...

Thanks VERY MUCH!!!! I would have NEVER figured that out on my own
