Columned text not showing up in Manipulate plot variable label

Question

I can't figure out why my columned text in the variables of my Manipulate plot are not showing up. In the labels for the variables, I set columns but only the top set of text is showing up. For example, I would like it to say "dairy herd" under "Beef (dairy herd)", etc.

Here is my code:

 Manipulate[
 Plot[

I am very new to Mathematica, so forgive my code for not being super clean! Also, please let me know if I can clarify something!

Answer 1

Here is a clean version of your code.

First, I convert some repetitive pieces of the code to functions, so that they can be reused easily.

Creating a function out of the big equation

f[bd_, bh_, l_, pm_, p_, o_, t_] := (((0.669207*(471 - bd) + 0.068928*(bd) + 
    1.91202*(1776 - bh) + 0.196938*(bh) + 0.764808*(495 - l) + 
    0.078775*(l) + 0.223096*(3793 - pm) + 0.022976*(pm) + 
    0.191202*(3995 - p) + 0.012694*(p) + 0.7520612*(333 - o) + 
    0.077462*(o)))*(t + 
   12) + ((0.49*(0.669207*(471 - bd) + 
       0.068928*(bd))) + (0.52*(1.91202*(1776 - bh) + 
       0.196938*(bh))) + (0.65*(0.764808*(495 - l) + 
       0.078775*(l))) + (0.17*(0.223096*(3793 - pm) + 
       0.022976*(pm))) + (0.46*(0.7520612*(333 - o) + 
       0.077462*(o))))*(2.707736 + (120.8001 - 
      2.707736)/(1 + (t + 12)/35.66701)^1.34428))/45

Creating functions out of the repetitive styles

style1 := Style[#, FontFamily -> "Oswald", Orange, FontSize -> {10}] &
style2 := Style[#, FontFamily -> "Oswald", Black, FontSize -> {5}] &

Now the design for the Manipulate interface becomes much more legible and easier:

Manipulate[
 Plot[
  f[bd, bh, l, pm, p, o, t], {t, 0, 100},
  AxesLabel -> {"years from now", "billion Kg CO2eq"},
  PlotRange -> {{0, 100}, {0, 15000}},
  PlotStyle -> {Orange, Thick},
  LabelStyle -> (FontFamily -> "Oswald"),
  Frame -> False,
  ImageSize -> {500, 380},
  GridLines -> {None, {{gl, Directive[Dashed, Gray, Thin]}, {2974.83, Directive[Dashed, Blue, Thick]}}},
  PlotLabel -> Column[
    {
     Style["EMISSIONS", FontFamily -> "Oswald", 14, Pink, Bold],
     " ",
     Row[{Round[f[bd, bh, l, pm, p, o, 100]], 
       " billion Kgs of CO2eq saved"}],
     Row[{bd, " gallons of water saved"}],
     Row[{bd, " acres of land saved"}]
     }, Alignment -> Center
    ]
  ],
 Pane[
  Column[{
    Style["FACTORIES CONVERTED", FontFamily -> "Oswald", 14, Orange, 
     Bold],
    Column[{
      Control@{{bd, 0, 
         Column[{style1["Beef (dairy herd)"], style2["dairy herd"]}]},
         0, 417},
      Control@{{bh, 0, 
         Column[{style1["Beef (beef herd)"], style2["beef herd"]}]}, 
        0, 1776},
      Control@{{l, 0, style1["Lamb"]}, 0, 495},
      Control@{{pm, 0, style1["Pigmeat"]}, 0, 3793},
      Control@{{p, 0, style1["Poultry"]}, 0, 3995},
      Control@{{o, 0, 
         Column[{style1["Other"]}, style2["wild game, horse, etc."]]},
         0, 333},
      Control@{{gl, 2974.83, style1["Target"]}, 0, 15000}
      }, Alignment -> Right]
    }, Alignment -> Center, Spacings -> 2],
  {300, 400},
  Alignment -> {Center}
