how to use switches on app designer

I am using Matlab app designer to create a gui for my unit converter. To do this i have decided to use a switch that will allow the user to flip between metric to imperial and imperial to metric. However, when i change the swtich to imperial to metric, the items in the drop box do not change. I have attatched my code, i hope someone can guide me in the right direction. I have tried using if statements to make this happen however it fails to register the changed value of the switch.

Thank you.

In line 40 of your code

if strcmpi(conversionvalue, 'temperature')  && strcmpi(switchvalue, 'imperial to metric')

the string which is coming from switchvalue is

'imperial to metric '

i.e. 1 space at the end

It is better to give switches values in items data

so now instead of passing the complete string it will pass 0 or 1

if strcmpi(conversionvalue, 'temperature')  && (switchvalue==0)

You can also apply similar strategy on conversion type
