Hierarchy scripting Child, Parent, Level of parent (Depth?)

[stantrolav]

Hello my dear solver of logic puzzles. Could you help me with something special?

In attachment you'll find file with 3 columns. From these 3 columns you must make table with maximum number in row [Level of parent]. Row [Name] is the name of cell in new table. [Parent] is "parent" cell for [Name]/ And Level is Number of column in our new table for Parent cell.

Have you understood this? Well, I need to make hierarchy. Help .
