I've a question about the code of chapter 4.
When i test the calculator in a webbrowser ( for the testing i used 4 browsers), it doesn't perform any calculations...
Is it about the script or is it a real working calculator? Am i missing something? Any HTML?, CSS? or JS?
The tool doesn't calculate the total of any order, but only reset to the start value.
I'm a noob when it comes to JS, so maybe i have missed something.
Could someone shed some light on my problem?
Thank you very much!
