Welcome to the forum @millmark443

Nice looking cost estimator.

If you want to spruce it up:

  • user selectable measurement system (metric vs imperial)
  • inputs for floor length and width, if people don’t have a calculator
  • ^ (add an area calculator)
  • rates for different types of floors (if applicable)
  • maximum and minimum floor area

Happy coding


Thank you, let me try this

Welcome to the Freecode camp Forums.

Good try!

I will recommend to put this on GitHub or GitLab (whichever favors you), and post the links from the repo from there.

It’s much neater to comment, and raise issues, and therefore pull requests as well.

But first, take into consideration what @teller suggested.
