Before
if mainList=='temperature'
if innerList1=='Celsius'
if innerList2=='Fahrenheit'
insert
mainList_options = handles.mainList.String;
mainList_value = handles.mainList.Value;
innerList1_options = handles.innerList1.String;
innerList1_value = handles.innerList1.Value;
innerList2_options = handles.innerList2.String;
innerList2_value = handles.innerList2.Value;
%at this point you really should check to be sure that the _value
%variables are not empty: if they are then it means nothing has been
%selected in that list.
%check for empty here
%then
mainList = string( mainList_options{mainList_value} );
innerList1 = string( innerList1_options{innerList1_value} );
innerList2 = string( innerList2_options{innerList2_value} );
