I am trying to make a lighting spell. I ram into a problem/bug with summon lightning with command block also has set up with filled clock too. I figure if you do /execute @e[type=!Player,rm=3,r=8] ~ ~ ~ summon LightningBolt do in chat box does works but if command block try do same command doesn't goes through. I did quick search on there seem anyone has same problem and not try to make a duplicates bugs.

these are most commands

/scoreboard objectives add SpellLBolt stat.useItem.minecraft.ender_eye

/scoreboard players test @p SpellLBolt 1

/scoreboard players set Daoverlordjr SpellLBolt 0

/replaceitem entity @a slot.hotbar.1 ender_eye 1 0

/replaceitem entity @p[score_SpellLBolt_min=1,score_SpellLBolt=1] slot.hotbar.1 dye 1 6

/tp @e[type=EyeOfEnderSignal] ~ ~-1024 ~

/testfor @p[score_SpellLBolt=1,score_SpellLBolt_min=1] {Inventory:[

]}

/execute @e[type=!Player,rm=3,r=8] ~ ~ ~ summon LightningBolt
