The people who are saying these things to you are not being rude nor unkind. If you asked this one-sentence question of a co-worker, who was therefore probably familiar with you and with what you're doing, he or she could "look over your shoulder" and probably help you. But when you ask a question on an Internet forum like this one, your question must be self-contained and "answerable." Please do carefully read the "effectively" link and try again.
