Several. First, you don't seem to understand that a question ends with ONE question mark.
Second, you failed to read the stickies at the top of the forum, or you would have learned that you need to POST YOUR CODE, and how to do it properly. Go read them now and do NOT screw up posting your code.
What can I do?
Write your code properly.
