Telephone Number Validator Project

The issue I am currently having is that when I do type in a valid number like 555-555-5555, the result would say that it is an invalid number thus not allowing me to past the rest of the tests.

I was also wondering why my code doesn’t show multiple results on the phone instead it rewrites the first result shown, thus making the clear button unnecessary

Can you post the link page pls?

you wrote your code so that whatever was the previous result it is overwritten

are you sure this is the way you pass a value to the function numCheck?

else if (numCheck(userInput.value)

This allowed me to finally get valid number results but I am unsure how i prevent the result from being overwritten and thank you for your assistance
