Why does this cause 8236 compile errors?

I add this bit of code to my map from WEU because I decided I didn't want to use advanced triggers, but did want to use these few functions.

But when I paste it into my custom map script, it tells me I have over 8000 compile errors during my next save, whats the problem?

Heres the code:
function WaitForSpecificUnitEvent takes unit U, unitevent E, real Time returns nothing
local trigger T = CreateTrigger()
call TriggerRegisterUnitEvent(T,U,E)
loop
call PolledWait(Time)
exitwhen GetTriggerExecCount(T) > 0
endloop
call DestroyTrigger(T)
set T = null
endfunction
function ChangeDamage takes unit U, boolean Increase, integer Zahl returns nothing
if not Increase then
set Zahl = 0 - Zahl
endif
call AddBonus(Zahl,U,0)
endfunction
function AddBonus takes integer amount,unit who,integer t returns boolean
return SetBonus((GetBonus(who,t)+amount),who,t)
endfunction
function StopSpellFromCasting takes unit U returns nothing
call DisableTrigger(GetTriggeringTrigger())
call PauseUnitBJ(true,U)
call IssueImmediateOrderBJ(U,"stop")
call PauseUnitBJ(false,U)
call TriggerSleepAction(0.01)
call EnableTrigger(GetTriggeringTrigger())
endfunction
function ChangeLife takes unit U, boolean Increase, integer Zahl returns nothing
if not Increase then
set Zahl = 0 - Zahl
endif
call AddBonus(Zahl,U,2)
endfunction
function ChangeDamage takes unit U, boolean Increase, integer Zahl returns nothing
if not Increase then
set Zahl = 0 - Zahl
endif
call AddBonus(Zahl,U,0)
endfunction
function SetBonus takes integer amount,unit who,integer t returns boolean
local integer bonus=amount
local integer array bit
local integer i=1
set bit[0]=1
loop
set bit[i]=bit[i-1]*2
exitwhen i==11
set i=i+1
endloop
call ClearBonus(who,t)
loop
if (bonus>=bit[i]) then
call UnitAddAbilityBJ(udg_zz_BnsBit[Ix(t,i)],who)
set bonus=bonus-bit[i]
endif
exitwhen i==0
set i=i-1
endloop
return (amount<=4095 and t<=3 and t>=0 and amount>=0 and who!=null)
endfunction
function ClearBonus takes unit who,integer t returns nothing
local integer i=0
loop
call UnitRemoveAbilityBJ(udg_zz_BnsBit[Ix(t,i)],who)
exitwhen i==11
set i=i+1
endloop
endfunction

Anyone have any idea what the problem is? I can't even save my map because WEU crashes, and I'm in serious need of update.

Because those functions may use variables or other functions.

The editor also tells you about 8690 errors when there is only one error.

ChangeDamage calls a function called AddBonus but that function is bellow the ChangeDamage function.

My solution: don't use WEU, or Use WEU the way you should and use Optimizer to remove the unused functions and variables

Yeah I know that they may use variables, and I'm positive that all of the variables are in the variable editor.

Btw I just looked at the part where it calls it yet it is below, but would that cause it to have a script error?

As for not using WEU, I'm trying that. I uncheck the box that says "Use advanced triggers" in WEU Enhancer (After removing all advanced triggers from my trigger editor, btw) and then the World Editor crashes the next time I try to save.

And the optimizer, is that YOUR optimizer or the one included with WEU?

hexenlordx, try moving the function that is called over the calling function.

vexorian, do you by any chance know when the code tags are getting back again? :/
