Which of the three problems do you think is caused by that code?
can you please tell me what to post?
Ideally, a minimal piece of code that demonstrates each problem (preferably something runnable), accompanied by both the output you get and the output you expect.
That's not always necessary, but you haven't given us much to go on. So far, you said you've got three errors, and you haven't shown how you've gotten any of them.
What you need to post is how you got each of those errors so that we can fix that "how".
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
Read Where should I post X? if you're not absolutely sure you're posting in the right place.
