Today i looked at the distributing and collection of gold and added it to the OnUpdate I posted yesterday.

The ultimate goal for me would be to be able to write a function which handles the distribution of buffmats, water and gold preraid. So one just needs to sitdown spamming the "1"-Key until all mages made n-stacks of Water, after that all the trading takes places (where every manaclass gets a stack of water, gold gets distributed, all buffmats gets distributed evenly among one class...).

FsMB_TradeGoldToLeaderAllBut = {Active = false, Amount = 25, Time = nil}
FsMB_GetMoneyFromLeader = {Active = false, Amount = 25, Time = nil}
SleepTime = GetTime()

function partyup()
 if IsControlKeyDown() then
  echo("Get Money from Leader Start!")
  FsMB_GetMoneyFromLeader.Time = GetTime() + 5
  FsMB_GetMoneyFromLeader.Active = true
  return 
 end
 if IsAltKeyDown() then
  echo("Trade Gold To Leader Start!")
  FsMB_TradeGoldToLeaderAllBut.Time = GetTime() + 5
  FsMB_TradeGoldToLeaderAllBut.Active = true
  return
 end
 ...

function TradeGoldToLeaderAllBut(amt)
 if not MB_raidleader then return end
 if MB_raidleader==UnitName("player") then
  if GetTargetTradeMoney()>0 then
   FsMB_TradeGoldToLeaderAllBut.Time = GetTime() + 5
   AcceptTrade()
   return
  end
    else
  local mymoney=GetMoney()
  if mymoney<=amt*10000 then
   FsMB_TradeGoldToLeaderAllBut.Time = GetTime()
   return
  end
  if CheckInteractDistance(RaidID(MB_raidleader),2) then
   FsMB_TradeGoldToLeaderAllBut.Time = GetTime() + 1
   if not MB_tradeopen then InitiateTrade(RaidID(MB_raidleader)) return end
   local mytrade=mymoney-amt*10000
   if GetPlayerTradeMoney()==0 then
    SetTradeMoney(mytrade)
   else
    AcceptTrade()
   end
  end  
 end
end
function GetMoneyFromLeader(amt)
 if not MB_raidleader then return end
 if MB_raidleader==UnitName("player") then
  local mymoney=GetMoney()
  if mymoney<=amt*10000 then
         Print("I don't have "..amt.." gold.")
   return
  end
  local mytrade=amt*10000
  if GetPlayerTradeMoney()==0 then
      SetTradeMoney(mytrade)
  else
      FsMB_GetMoneyFromLeader.Time = GetTime() + 5
      AcceptTrade()
  end
 else
    local mymoney=GetMoney()
    if mymoney>amt*10000 then
  FsMB_GetMoneyFromLeader.Time = GetTime()
     return
    else
     FsMB_GetMoneyFromLeader.Time = GetTime() + 1
    end
    if GetTargetTradeMoney()>0 then AcceptTrade() return end
    if not MB_tradeopen then
  InitiateTrade(RaidID(MB_raidleader))
  return
    end
 end
end

local function UpdateHandler()
 local CurrentTime = GetTime()
 
 ...
 
 if FsMB_TradeGoldToLeaderAllBut.Active == true then
  if FsMB_TradeGoldToLeaderAllBut.Time < CurrentTime then
   FsMB_TradeGoldToLeaderAllBut.Active = false
   echo("Trade Gold to Leader End!")
  else
   if SleepTime < CurrentTime then
    SleepTime = CurrentTime + 0.5 
    TradeGoldToLeaderAllBut(FsMB_TradeGoldToLeaderAllBut.Amount)
   end
  end
 elseif FsMB_GetMoneyFromLeader.Active == true then
  if FsMB_GetMoneyFromLeader.Time < CurrentTime then
   FsMB_GetMoneyFromLeader.Active = false
   echo("Get Money from Leader End!")
  else
   if SleepTime < CurrentTime then
    SleepTime = CurrentTime + 0.5 
    GetMoneyFromLeader(FsMB_GetMoneyFromLeader.Amount)
   end
  end
 end 
end

Hopefully i didn't make to many mistakes merging your latest SM_Extend.
