I'm trying to use SmartAOE and I keep getting an error when it tries to call for the spell save DC     This is a fireball macro I found but nothing else I have tried is working either.  Is there a new way to call for the Spell_Save_DC?    !smartaoe {{    --controlTokName|GenericSpellAoE    --controlTokSize|8    --controlTokSide|5    --aoeColor|#99000050    --instant|1    --gridColor|#99000050    --aoeType|circle, float    --radius|20ft    --forceIntersection|1    --minGridArea|0.25    --minTokArea|0.25    --fx|burn-fire    --dc|@{selected|spell_save_dc}    --saveFormula|5eDEX    --damageFormula1|[[(5+?{Cast at what level?})d6]]    --damageType1|Fire    --ignore|SmartAoE_Ignore,1        --autoApply|1    --bar|1    --zeroHPmarker|dead    --desc|A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an explosion of flame.
