Toggling Switch by using an item

[JustX]

Hey it's me again,
I've got the following question:
I try to use an item that toggles a switch while using it outside or inside.
So the script:

ItemHandlers::UseFromBag.add(:XXX,proc{|item|
$game_switches[130]=!$game_switches[130]
next 2
})

When I try to use it, it says "You cant use that here!"
Why? And what do I change?

Thx, JustX

This code will check if it's outside, as written by KleinStudio.

def isOutside? # Only refresh when it's indoor
  isoutdoor=pbGetMetadata($game_map.map_id,MetadataOutdoor)
  if $game_map && (!isoutdoor or isoutdoor==false)
      return false
  end
  return true
end

Try something like

ItemHandlers::UseFromBag.add(:XXX,proc{|item|
if isOutside?
$game_switches[x] = true
elsif !ifOutside?
blabla
end
next 1
})

It still says that I cant use it there,
What should I change? I dont get it..

ItemHandlers::UseFromBag.add(:BATTLECAMERA,proc{|item|
   $game_switches[BREAKDOWN]=!$game_switches[BREAKDOWN]
   Kernel.pbMessage(_INTL("Switched the Battle Camera {1}.",($game_switches[BREAKDOWN]==true)?"on":"off"))
   next 1
})

ItemHandlers::UseInField.add(:BATTLECAMERA,proc{|item|
   $game_switches[BREAKDOWN]=!$game_switches[BREAKDOWN]
   Kernel.pbMessage(_INTL("Switched the Battle Camera {1}.",($game_switches[BREAKDOWN]==true)?"on":"off"))
   next 1
})

This is code I used to make the Battle Camera work. It should be what you're looking for.
