Olá!

Estou estudando OutSystems e não consigo passar da página 40.

Parece que ao criar o Menu para "Movies", apresenta este erro.

"Required Property Value : A valid expression must be set for parameter 'MovieId'."

Já revir a caderno de exercício e não encontro onde eu errei.

Ao criar o Menu para "People" não deu erro.

Outra coisa que me chamou atenção é que o Menu não aparece no Studio abaixo do cabeçalho, pois segundo o caderno de exercício ele apareceria automaticamente.

Hello!

I'm studying OutSystems and I can not get past page 40.

It looks like to create the Menu for "Movies", to display this error.

"Required property value: A valid expression must be defined for the 'MovieId' parameter."

Already reviewing a workbook and not finding where I went wrong.

When creating the Menu for "People" did not give error.

Another thing that caught my attention is that the Menu does not appear in the Studio below the header, so according to the workbook it would appear automatically.

From your screen shot your "Movies" page requires a "MovieId" input parameter. (Your "People" page is not expecting an input parameter.

That would seem unusual for a page which sounds like a list of movies. OutSystems is asking you to supply a value/variable for that parameter.

I would suggest 

1. you check if you "Movies" page really needs a parameter (as it sounds like a list of Movies and it would seem unlikely that it would expect a specific MovieId as a parameter) if it does not need a parameter then delete it from the page.

2. If it does need a parameter then either supply the value/variable or set it to NullIdentifier()
