why red underline on favoritenumber ?

Hi there, Vivek

Try adding a space between uint256 and _favoritenumber. Here, uint256 shows what kind of variable it is, and _favoritenumber is the actual variable name.

Also, make sure to be consistent with the names you give to your variables:

• Notice that favoriteNumber and _favoriteNumber are different variables because of the underscore at the beginning of the name.
• However, even favoriteNumber and favoritenumber are different variables because you did not capitalize the n in the latter.

In the future, if you have similar errors try looking at Patrick's code in the repository associated with the lesson you're on.
