Blizzard stopped the ability to use multipule casts within 1 macro. It will use the first spell and then error out.

So the example:

/castsequence [yourdpstargettingschemehere] judgement X, crusader strike, divine storm,, crusader strike, judgement X,,
/cast [target=tank] flash of light

Should not work.

As the first castsequence is used. The 2nd should never be used.
