Reverend Jim is correct. To get support from various expertise you must have to show your effort, from which every one can understand for what cause you didn't get your desired result.

You don't have to upload a picture. Just post your code and tell us what isn't working. You've told us what you want to do but not where you are hung up. We are not going to write your code for you. That's not "help me". That's "do this for me".
