Bug? Wrong warning on a variable

[abilio486software]

Hello, For some reason, in this class, "Error" variable is (in my opinion) wrongly considered as an "Unused variable".
"Erro" variable is used, even initializyed, and filled with messages.
I think this could be a bug in B4A.

The warning is correct.
You declared the variable: Dim Erro As String
You have given it a value: Erro = ""
But have never used it, like: Label1.Text = Erro
