Your previous post seems to indicate you have solved the problem, so it isn't clear what help you now require. Can you elaborate on your current issue? If there is an error, post it. If the problem is with the runtime behaviour, can you explain what you are actually seeing versus what you expect to see?

If possible, post a minimal code example that demonstrates the error or behaviour. Try to isolate the problem from the rest of your code.
