Please see my amendments to your post in red. Remember to use correct capitalisation and punctuation. Every sentence must begin with a capital letter and end with the appropriate punctuation mark. Do not put a space before a question mark.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
