Hi Dana,

Your first problem is that your raise ValueError if: product_idea is les will never be executed. The previous line is a return statement and any line that is executed that returns will always end execution of the function.

This means you need to test whether product_idea is less than 3 characters long before you get to the return line.

It looks like you might still be confused with the syntax for if, so consider rewatching If, Else and Elif. Or look at the official Python docs for if statements. In short, you need to start with if then your condition, then the : character.

Once inside the if branch you need to write the code that should execute if your condition is met, so assuming your condition tests whether product_idea is less than 3 characters long, the code inside the branch will do whatever you want to happen for situations where the product_idea is less than 3 characters long. This is where you would raise your ValueError.

It also looks like you're unclear about how to check the length of a string. Here you want to use the len() function (not "les" which is what you have).

Once you know the length of the string, you can compare it to the value 3. You can find an explanation of Python's comparison operators in the official docs. You will want to use the "less than" operator, which is the < symbol.

Hope that clears everything up for you.
