Hi there!

To convert a string to an integer you can use String.to_integer/1 e.g.

int = String.to_integer("1")

When it comes to user input you might also want to remove whitespace first which you can do with String.trim/1.

Hope that helps!

Edited for code blocks. I recommend formatting code that you post, it helps others understand what’s going on to help you better.

In your case you wrote :string.to_integer but @tyro wrote String.to_integer. Elixir module names capitalized, erlang modules tend to be lower case. That’s why :rand.uniform uses lower case :rand, it’s an erlang module. String however is an Elixir module, you can find the documentation on it here: https://hexdocs.pm/elixir/String.html
