Radiobutton

May 3 2022 4:09 PM

Dear sir,

I made two radio buttons for converting the temperature. Radiobutton1 converts the temperature from Celsius to Fahrenheit and Radiobutton2 the other way around. But when I click on Radiobutton2, my output is always 0. What am I doing wrong?

With sincerely,

Steve
