Ashwin - one problem with your conversiontypeDropDownValueChanged callback, you are using the same variable name for to represent two different values
value = app.converstiontypeDropDown.Value;
value = app.Switch.Value;
if strcmpi(value,'temperature') && strcmpi(value, 'metric to imperial')
% etc.
end
Try renaming the variables to distinguish one from the other and to give you an idea as to what each represents.
conversionValue = app.converstiontypeDropDown.Value;
switchValue = app.Switch.Value;
if strcmpi(conversionValue,'temperature') && strcmpi(switchValue, 'metric to imperial')
% etc.
end
Also, please include attach your code rather than a screen shot of it.
