Odd PopulateList Function Behavior

[GeneN]

I'm writing an LTP that identifies revealed resources and have encountered behavior that is very perplexing. The behavior occurs when parsing the code in a <PopulateList> element. Below is the code that results in the following message in the Lua Console:
(Syntax Error: [string "return function()..."]:41: end expected (to close function at line 1) near '<eof>')

If the single line containing "local temp3 = 0" is removed, there is no syntax error and the panel loads as expected.

I am completely stumped. Any suggestions will be greatly appreciated.

      <PopulateList>function()
          print("Test Resource Pin list")
          local resourcePinList = {}
          if efn_ResourcesToLocateList then
            print("Resource count: " .. #efn_ResourcesToLocateList)
            local resourceIndexesToLocate = {}
            local resourcePinData = {}
            local idxPlayer, Player, playerVis
            local idxLoc, resName, idxRes
            local temp1 = 1
            local temp2 = 1
            local temp3 = 0
            idxPlayer = Game.GetLocalPlayer()
            playerVis = PlayersVisibility[idxPlayer]
            player    = Players[idxPlayer]
            -- add efn_ResourcesToLocateList items to resourceIndexesToLocate consistent with efn_OnlyRevealedResources
            for idxLoc, resName in ipairs(efn_ResourcesToLocateList) do
              if (not efn_OnlyRevealedResources) then
                resourceIndexesToLocate[resName] = efn_ResourceDataByName[resName].Index
              end
            end
            -- create a table of pin location data for plots containing resourcesToLocate consistent with efn_OnlyRevealedPlots.
            local idxPlot, plotRevealed, plot, resType
            for idxPlot = 0, Map.GetPlotCount() - 1 do
              plotRevealed = "no"; if playerVis:IsRevealed(idxPlot) then plotRevealed = "yes" end
              if (not efn_OnlyRevealedPlots) or (plotRevealed == "yes") then
                plot = Map.GetPlotByIndex(idxPlot)
                resType = plot:GetResourceType()
                for resName, idxRes in pairs(resourceIndexesToLocate) do
                  if resType == idxRes then
                    local x = plot:GetX()
                    local y = plot:GetY()
                    table.insert(resourcePinData, {resName, idxPlot, x, y, plotRevealed})
                    table.insert(resourcePinList, resName .. ";" .. idxPlot .. ";" .. x .. ";" .. y .. ";" .. plotRevealed)
                    break
                  end
                end
              end
            end
          end 
          return resourcePinList
        end
      </PopulateList>
