Thanks for your answer.
Before I finish this answer, when I have finished building my spreadsheet model of this, could you check the spreadsheet for me? and how much will the charge be for this, if possible?
If this is possible, I know that justanswer do not allow attachments, so I do not know how to get this spreadsheet to you. If you could provide some way, that would be great.
Thanks for email.
I will setup a new question in a week or 2 weeks with a spreadsheet of my model. So you can check this. So watch this space!
For now I will finish this question. Thanks for your help.
