There are quite a few things that need fixed in this code. I’ve made some changes and put in comments explaining why I changed the things I did.
local composer = require( "composer" ) local json = require "json" -- -- Do your requires at the top unless there is a good reason to not need it defined until later. -- local physics = require "physics" local scene = composer.newScene() local myGridlvl1 local myGrid2lvl1 local myCircle1 local button1 local timer1 -- -- Indent your code. It helps you line up your "end"s with their function/if/while/repeat's. -- local function down (event) myCircle1.y = myCircle1.y + 0 end local function movelevel1(event) myGridlvl1.x = myGridlvl1.x - 4 myGrid2lvl1.x = myGrid2lvl1.x - 4 end local function tap (event) myCircle1.y = myCircle1.y - 20 end function endGamelevel1() local endtext1 = display.newText ("You lost!", 160, 50, font, 32) endtext1:setFillColor (0,0,0) timer.cancel(timer1) Runtime:removeEventListener( "enterFrame", onUpdatelevel1 ) Runtime:removeEventListener( "enterFrame", down ) Runtime:removeEventListener( "enterFrame", movelevel1 ) myCircle1:removeEventListener("collision", myCircle1) button1:removeEventListener( "tap", tap ) local function restart (event) composer.gotoScene( "restart1" ) end local restartbutton1 = display.newImage("restart.png", 150, 200, 100, 100) restartbutton1:addEventListener( "tap", restart ) end local function Collision(self, event) if (event.phase == "began") then if (self.ID == "Circle1" and event.other.ID == "Crash1") then endGamelevel1() end end end local function level2 (event) Runtime:removeEventListener( "enterFrame", onUpdatelevel1 ) Runtime:removeEventListener( "enterFrame", down ) Runtime:removeEventListener( "enterFrame", movelevel1 ) myCircle1:removeEventListener("collision", myCircle1) button1:removeEventListener( "tap", tap ) composer.gotoScene("tolvl2") end local function onUpdatelevel1 (event) if (myGridlvl1.x \< 100) then myGridlvl1.x = 160 if (myGrid2lvl1.x \< 100) then myGrid2lvl1.x = 160 end end end function scene:create( event ) local sceneGroup = self.view physics.start() physics.pause() -- -- This really should be in main.lua and not in the scene file unless you want to hide the -- the status bar just for this level.

I never got the error you got, but I did get errors for missing image files (which I had to create). If you use this code and you’re getting errors, make sure you have all your image files in the folder with your main.lua.
