Welcome back.
So before publishing your application, you need to make sure that you are that you reviewed your record
carefully because trust me, there could be errors in your code you, you could have some typos, some
mistakes.
So you need to test your application before publishing it.
And as you can see here, I have a problem.
I have a an error here, which is using the class attribute attribute or twice.
I should, of course, I shouldn't be using the class attribute twice.
I shouldn't be using it only once.
And as you can see, this is a simple error, but these errors happen.
No matter how experienced you are, you will.
You will make these mistakes.
In order to fix these these mistakes, you need to review your code and go through your code carefully
before publishing your application.
So in order to fix this, you see this area need to remove this class.
Obviously, with the main here, and then you need to move them over to the ear, to the class attribute
here.
So this is the fix for this mistake.
And again, you need to review your code one more time in order to avoid any problems with your code.
