I strongly advise against using local timers (destroying timers and nulling timers have a lot of issues). Try to use a stack of global timers so you can recycle timers. I believe there are tutorials on that out there.

I'm curious though, why do you use empty else clauses? Not that it should affect anything - I just think that's weird.

And can you give us a few samples of errors in your code?

The whole function was error

JASS:
function Trig_Nuke_Conditions takes nothing returns boolean
    return GetSpellAbilityId() == 'A009'
endfunction

function Nuke_Effect takes nothing returns nothing
  local timer t = GetExpiredTimer() //Expected A Name
  local unit dummy = H2U(GetHandleHandle(t, "dummy"))//Expected Expression
  local real ang = GetHandleReal(t, "ang"))//Expected Expression
  local real i = GetHandleReal(t, "ang"))
  local location = GetUnitLoc(dummy)
  call SetUnitPosition(dummy,GetUnitX(dummy) + 20 * Cos(ang * bj_DEGTORAD),GetUnitY(dummy) + 20 * Sin(ang * bj_DEGTORAD))
  set i = i + 1

  if i == 100 then
  set dummy = CreateUnitAtLoc(GetOwningPlayer(dummy) , 'u004', o, ang )
  call SetUnitPathing(GetLastCreatedUnit(), false)
  call SetUnitFlyHeightBJ( GetLastCreatedUnit(), 0.00, 200.00 )
  else
  endif

Also this is the Local Handle Vars. I'm not sure if I did it right, but I replaced the InitGameCache("jasslocalvars.w3v") with a global variable - cache, game cache.

First of all.

JASS:
  if i == 100 then
    //set dummy = CreateUnitAtLoc(GetOwningPlayer(dummy) , 'u004', o, ang )
    call SetUnitPathing(GetLastCreatedUnit(), false)
    call SetUnitFlyHeightBJ( GetLastCreatedUnit(), 0.00, 200.00 )
  endif

GetLastCreatedUnit() will return null, since it will only return the last created unit if you did it with the BJ function, CreateNUnits. Why not just use a local unit variable?

JASS:
  if i == 200 then
    call RemoveUnit(dummy)
    call PauseTimer(t)
call FlushHandleLocals(t)
    call PauseTimer(t)
    call DestroyTimer(t)
  endif

Pausing the timer is unnecessary.
I can only recomment TimerUtils. Everyone should use that one.

Why do you convert the coordinates to degrees? You do 2 bj_DEGTORAD calls every 0.03 second. If you just stay with radians you only need to do 2 bj_RADTODEG, the 2 where you create your units.

And don't use locations, they're slow. Just use coordinates instead.

Why do you declare a variable called "bomb" and save store it in the timer? You never use it.

I don't know what the problem is, but your timer will never stop. The problem is, that you store the integer "i", but you never increase the stored value, hench it will stay 0.
