Hi Bob,

A small correction to your second suggestion pasted below:

varData = {{"Emissions", {"None", "1000GtC", "3000GtC", 
     "5000GtC"}}, {"Weathering scheme", {"Globavg", "GKWM", 
     "GEM_CO2"}}, {"Ca weather feedback", {"On", 
     "Off"}}, {"Si weather feedback", {"On", "Off"}}};

Module[{n = 1}, 
 Manipulate[Evaluate[Table[v[n], {n, Length[varData]}]], 
  Evaluate[
   Sequence @@ (Inner[{{v[n++], #2[[1]], #1}, #2} &, 
      Sequence @@ Transpose[varData], List])]]]


Note I have changed:

> Length[varvalues]-->Length[varData]


to be consistent with your recommendation (which if it were used) would not define varvalues in addition to varData:

> I recommend that you enter and store the titles and values together to keep them linked
