My Dear Holger, I owe you Million Salutes for this help. Thank you soo much!

Regarding your suggestion for reviewing the formulas and sections, can you please tell what exactly you mean? Because, objective of this project is to compile delivery performance data and put the reasons for failure in pareto and pie chart. So, I am thinking in one direction and I have none who will check the correctness of what I am doing. If you give me the details, I will check again and correct them.

Many thanks for the help you are providing.

Regards,
