Step 32

Number inputs only allow the e to occur between two digits. To match any number, you can use the character class [0-9]. This will match any digit between 0 and 9.

Add this character class before and after e in your pattern.

WARNING

The challenge seed code and/or your solution exceeded the maximum length we can port over from the challenge.

You will need to take an additional step here so the code you wrote presents in an easy to read format.

Please copy/paste all the editor code showing in the challenge from where you just linked.

Replace these two sentences with your copied code.
Please leave the ``` line above and the ``` line below,
because they allow your code to properly format in the post.

Hey.
Sorry, your code does not pass. Keep trying.

You should add the [0-9] character class after e in your regular expression.

Hey ,
Try this one when you make post try to tell what’s going on and also add code by adding 6 backticks than in between those backticks add your code.
Happy coding

const regex = /e[0-9]/i;

  const regex = /e[0-9]/i;
}```

Same error but now 
You should add the [0-9] character class before e in your regular expression.
"class before" not after )) Mb it's problem with code editor?

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
