Hi, im trying to assign a newText on a column on Parser, i have a newText calling Highscore and i want to assign it to a column in Parse calling Highscore. 

im trying to do this but it doesn’t work

  local function onCreateObject( event )   if not event.error then    print( event.response.updatedAt )   end end parse:createObject("\_User", {["Highscore"] = Highscore},onCreateObject)

i have the login code and i want to assign the Highscore value to the user logged in

     local function onLoginUser( event )   if not event.error then     storyboard.gotoScene("start", "slideLeft", 800)        --check if user is verified   end end parse:loginUser( { ["username"] = loginUserNameTextField, ["password"] = loginPassTextField}, onLoginUser )
