Nobody out here is going to solve your problem completely and hand it over to you.
Attempt it yourself and post whatever you've done here and we'll help you with the rest of the flowchart.
If you've never worked with flowcharts before, click here.

Are you receiving any errors? Does this code not work that way you intended it? When asking for help there are a couple items that are vital in order for someone to properly help you:
- Post the code you're having problems with
- Post the exact error you're receiving, if you are receiving one
- If no error explain what the code is doing versus what you want it to do
- Post your question in the body of your post, not the description field
