title: What's Return & what am I doing wrong(Lua)
body: <p>I have two questions, one being what is return in lua? I have been searching all over the internet looking for what it does/means and its purpouse. 2. I am having trouble coding this section:</p>
  
  <pre><code>testGrade={}
  testGrade.Joe = 86
  testGrade.Josh = 75
  testGrade.Jack = 12
  testGrade.Andrew = 0
  testGrade.Larry = 100
  testGrade.Noah = 94
  testGrade.Blakely = 67
  
  for k,v in pairs(testGrade) do
      local maxGrade = 100
      if testGrade[grade] == 100 then
          Msg("Congratulations "..k..", you scored a "..v.." out of "..maxGrade.." getting every question right!\n");
      elseif testGrade[grade] &gt;= 90 then
          Msg("Congratulations "..k..", you scored a "..v.." out of "..maxGrade.." getting an A!\n");
      elseif testGrade[grade] &gt;= 80 then
          Msg(k..", you scored a "..v.." out of "..maxGrade.." getting a B.\n");
      elseif testGrade[grade] &gt;= 70 then
          Msg(k..", you scored a "..v.." out of "..maxGrade.." getting a C, try harder next time.\n");
      elseif testGrade[grade] &gt;= 60 then
          Msg(k..", you scored a "..v.." out of "..maxGrade.." getting a D, you need to study!\n");
      elseif testGrade[grade] == 0 then
          Msg(k..", you scored a "..v.." out of "..maxGrade.." getting NOTHING right! Did you even try?!\n"); 
      else
          Msg(k..", you scored a "..v.." out of "..maxGrade.." making you fail. You need to try harder and study!\n"); 
      end
  end
  </code></pre>
  
  <p>I was trying to do some practice coding, but I got stumped on this. Commenting is very helpful ;)</p>
