React Calculator is not passing FCC tests

Hello,

I just finished making the React part of my calculator app and it seems to be working just fine. I tried doing everything I have imagined to break it and it seems to be showing correct results and working in a similar fashion to the calculator showed as an example.

However it fails tests #9 and #11-15. I manually tried inputting those values showed in the test failure messages and got a correct result but the tests are looking something like this:

I don’t really understand why it shows that my output is ‘0’ when it is not. Here is my pen.

Thanks in advance for you help,
Konstantin

Hello there,

Your issues that you have not made the elements with id’s one, two, three... clickable:

Give the button the id, and you should pass more tests.

Hope this helps
