App Designer - How do I set limits for different variables?

Hello just wondering if someone can please help me.

Under the directiondropdown callback, I am wanting to set a limit of [-inf inf] for 'Temperature' unit types ie. 'Celcius to Farenheit' and 'Farenheit to Celcius' and a limit of [0 inf] for all other unit types ie. 'Pressure', 'Volume' and 'Energy'. When a user inputs a value, I am wanting the program to convert both negative and positive values for temperature, however only positive values for all other unit types. How do I go about this?

Thanks

From my understanding you want to set limits to variables in App Designer. You can user “Limits” property of uieditfield to set the limits. You can refer NumericEditField Properties for more information.
