    The error tells you, that the Reference you are trying to use is "null". References don't always have values. It's like a finger pointing to the thing you want to use,
    but it can also point to,.. nothing. If that's the case, you are not allowed to access it and the error "Accessed None" returns.

    The Error happens in "OnClicked (Login)". The "GetField" seems to not return anything and calling "As String" on it, is resulting in "Accessed None".

    Before you use your References (Called "Pointers" in C++), make sure to use "IsValid" node on them. Doesn't matter which one of the both, one just needs
    the Branch as an additional node, cause it only returns true or false.

    So the field name "result" seems to be wrong?

      Sorry i saw this a bit late, i started from scratch and doing it another way, i traced it down to the root of problem but everything seemed to be correct and i redid it 4 times so i just kinda gave up on that way.


        Draugole how you did that? I'm having that error...

        Forget, It's working
