Mapping new Weather Gear

I'm been trying to figure out how to map other gear so it function the same as the obi's or twilight cape.  I wanted to set chatoyant staff using something like gear.ElementalStaff the same was i would for the obis in the midcast set.  However no matter how i try to map this i can't get it to work.  Any suggestions?  

Here's an idea of what I'm trying to do:

WHen casting cure on lightday or lightsweahter i want my main to equip chatoyant staff and sub enki strap. And when there is no weather i want my main to default to gada and sub genbu's shield.  

This would mirror how the obis defualts to bishops sash.

However, there is no current rule like this and i have been trying to map it like the obi was map but I can't get it to work.  Any help would be greatly appreciate.  Thanks~

like this
 

if S{'Cura','Cura II','Cura III','Curaga','Curaga II','Curaga III','Curaga IV','Curaga V','Cure','Cure II','Cure III',
    'Cure IV','Cure V','Cure VI'}:contans(spell.name) and 
    (world.day == "Lightsday" or S("Auroras","Stellar glare"):contains(world.weather)) then
    --equip chatoyant staff and sub enki strap
else
    --equip gada and sub genbu's shield
end

thanks...Got it to work
