Beth, who said you were stupid? I did not.
Your original post, that you deleted, asked: "tell me what to try next". That's all. No other information. It came across, at least to me, like you can't be bothered to think it through and want us to do all the work and "tell you what to do". In fact, I had already answered that question in your other thread - the one I linked - which is why I linked it.
I am trying to get you to make your own decisions because there is no reason that I know of why you can not. That means I think you are capable of it. The reason this board exists is to exchange experiences and to learn from what is discussed here. That is all I am trying to make happen. If you find that offensive, I am sorry. But I can't tell you what to dose your cat. I can only make suggestions and explain why I am making them so that YOU can decide what to do.
