You are very close! You need to check the length of the passed in argument instead of checking the length of the fix string "dende”.

Post back if you need more help. Good luck!!!

There are two general terms referring to data passed to a function: parameter and argument

When defining a function, the parameters are listed in parens following the name of the function. Below, product_idea is the parameter:

def suggest(product_idea):

When a function is called, a list of arguments are listed in parens followers no the function name. If no argument are supplied, the parens are empty. 

# calling function 
suggest('cake')

# should return “cakeinator”

The code challenge checker will call your function with various arguments to evaluate its behavior. Since your code does not utilize the product_idea parameter, using instead a fixed string "dende”, then the length Idea will always 5 and the ValueErrror would never be raised. 

    Idea = len("dende") # always 5
    if Idea < 3:  # always False

So, replace "dende" with product_idea
