Help with Elem Shaman Macro

[Hellektro]

Hi there. I have an issue where the last line of the Elem Shaman macro is not firing in my macro. It never casts the Lightning Bolt part but everything else works fine. Am I missing something here? Thank for any help.

/run SetCVar("Sound_EnableSFX","0")

/use 10
/use 13
/cast Blood Fury
/cast elemental mastery

/click sdf__DPS1
/click sdf__DPS2
/click sdf__DPS3
/click sdf__DPS4

/run SetCVar("Sound_EnableSFX","1")
/script UIErrorsFrame:Clear()

The actual lines are

/castsequence reset=combat flame shock,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
/castsequence reset=combat lava burst,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
/castsequence reset=combat chain lightning,,,,,,,,,,,,,,,,,,,,,,,,,
/cast lightning bolt
