problem with variable and function

Below is pasted the function which is looking for the "funcs"
dictionary, as well as the dictionary. They appear in my py file in
this order, yet I get an error in nextMode() that "global name 'funcs'
is not defined". Oddly, the keys dictionary works fine; it is defined
above the nextMode function.

def nextMode():
 global HOTKEYS
 global HOTKEY_ACTIONS
 global mode
 global modes
 global modeNum
 global modeNames
 global funcs
 #mode=mode+1
 #check to make sure the newly selected mode is enabled
 tmp=0
 while(tmp<modeNum):
  mode=(mode+1)%modeNum
  if(sys.modules[modeNames[mode]].enabled=='True'):
   break #break on the first enabled mode we find
  #end if
  tmp+=1
 #end while
 HOTKEYS=keys[mode]
 HOTKEY_ACTIONS=funcs[mode]
 registerHotkeys()
 speak("Now in "+str(modes[mode])+" mode.")
#end def

#we now have the default mode to be used, but what if it is disabled?
if(sys.modules[modeNames[mode]].enabled=='False'):
 nextMode()
#end if

funcs=[]
#this dict MUST be defined after all the functions it uses have been
#ARM function dictionary
funcs.append({
  1 : exitProgram,
  2 : arm.sayLoad1,
  3 : arm.sayLoad2,
  4 : arm.sayLoad3,
  5 : arm.sayLoad4,
  6 : arm.sayProcAvg,
  7 : arm.sayUsedRam,
  8 : arm.sayDisk1Info,
  9 : arm.sayDisk2Info,
  10 : nextMode,
  11: clipboard.toClipboard
})

#weather function dictionary
funcs.append({
  1 : exitProgram,
  2 : weather.getCurrent,
  3 : weather.getToday,
  4 : weather.getTomorrow,
  5 : weather.getTwoDays,
  6 : weather.getThreeDays,
  7 : weather.switchLocation,
  8 : arm.sayDisk1Info,
  9 : arm.sayDisk2Info,
  10 : nextMode,
  11 : clipboard.toClipboard
})
funcs.append({
  1 : exitProgram,
  2 : network.speed,
  3 : arm.sayLoad2,
  4 : arm.sayLoad3,
  5 : arm.sayLoad4,
  6 : arm.sayProcAvg,
  7 : arm.sayUsedRam,
  8 : arm.sayDisk1Info,
  9 : arm.sayDisk2Info,
  10 : nextMode,
  11 : clipboard.toClipboard
})


HOTKEY_ACTIONS=funcs[mode]
