JavaScript error [solved]

code: https://code.sololearn.com/Wef7Rvg7wRiT/?ref=app problem: My code here is not working. The function validate() thinks that final is undefined, but I declared final before the function is being called. I also get a syntax error in the code. Please help!!!

The link below explains variable scope. In your case, the problem is function scope. https://javascript.info/var#var-variables-can-be-declared-below-their-use Basically when declaring a variable in one function that variable can not be accessed by another function. but if you declare a variable outside of any function that variable becomes a global variable and is accessible by any function within the global scope, hence Russ suggested solution.

ODLNT Final starts with: <h3><a target="_blank" href="https://github.com/' + data.login + '">' + data.login + '</a></h3><img class="w3-round" src="' + data.avatar_url + '">' Then I want to add the follwing to the end of the string if it isn’t equal to null or “”: '<p>' + data.bio + '</p>' '<p>Followers: ' + data.followers + '</p>' '<p>Following: ' + data.following + '</p>' '<p>Repositories: ' + data.public_repos + '</p>' '<p>Gists: ' + data.public_gists + '</p>'

Russ The problem is that the variable does not exist when the funstion is being called do that doesn’t work.

What should be assigned to the variable final before it is concatenated with fill?

My suggestion is to declare final outside the functions, then just set it to what you want inside them. Example: var final; function validate() { final = ... } Also, on line 2, I think you should use && rather than ||.
