What do you mean by phase ?
Is it about a project you already have implemented ?
If so, please post it here.
Then indicate clearly (and not just as a single sentence in the title)
What you are wanting to do, what you already tried, what you expect what you tried to do, what you experience it actually doing.
Provide as much clear details as you can.
