Cannot be Summoned/Set

Subject: Cannot be Summoned/Set Wed Jan 14, 2015 9:09 pm

I'm not sure if I'm doing this right... Okay, I'm 99.9% sure I'm not doing this right, since it's not working and I'm asking for help.

The monster effect is "Cannot be Summoned/Set while you control a non-Spellcaster-Type monster." But I can't get it to work properly. It's still allowing all summons.

Code:: function c780001.initial_effect(c)
--Cannot be Summoned if non-Spellcaster exists
local e=Effect.CreateEffect(c)
e1:SetType(EFFECT_TYPE_SINGLE)
e1:SetCode(EFFECT_CANNOT_SUMMON)
e1:SetRange(LOCATION_HAND)
e1:SetCondition(c780001.sumcon)
c:RegisterEffect(e1)
local e2=e1:Clone()
e2:SetCode(EFFECT_CANNOT_SPECIAL_SUMMON)
c:RegisterEffect(e2)
local e3=e1:Clone()
e3:SetCode(EFFECT_CANNOT_FLIP_SUMMON)
c:RegisterEffect(e3)
local e4=e1:Clone()
e4:SetCode(EFFECT_CANNOT_MSET)
c:RegisterEffect(e4)
end

Code:: function c780001.sumfilter(c)
return c:IsFaceup() and c:GetRace()~=RACE_SPELLCASTER
end
function c780001.sumcon(e)
return Duel.IsExistingMatchingCard(c780001.sumfilter,e:GetHandlerPlayer(),LOCATION_MZONE,0,1,nil)
end
