    The codebank forum is made for sharing code with other people, not to post a question about a problem. I asked the moderators to move you thread.

    Beside that we need more information if you want some help : post the complete error message and the code that provoke the error and a clear explanation of the problem.

    Well that at least sounds good in that you must have Option Explicit turned on so you have to declare all your variables, and the error is telling you that at some line of code you are referring to a variable that is not available from that location.

    When you declare a variable, the code that can refer to that variable can be limited, which is referred to as the Scope of the variable.
    To identify the cause of your error, we need to know what the name of the variable is, and where the variable is declared.

    I would suggest doing a web search on "vb.net variable scope" and do some reading up on the topic. You may be able to solve the issue yourself and learn more in the process than having us identify a single instance of scoping issue that you may have in your existing code.

    The only reason that you would get an error message telling you that a variable is not defined is because a variable is not defined. The solution is to define it. Maybe it would help if you were to show us the code in which the error message is generated and the code in which you think you have defined the variable, given that we have no psychic powers to see what you did wrong if we can't see what you did. We can make guesses or assumptions but then we could guess or assume wrong. We should not have to guess or assume anything that you already know, because you can tell us.

    Given that Option Explicit is On by default, I'm not sure that any congratulations are in order for that fact. It's Option Strict that is Off by default and should be turned On immediately.
