I initialize it by calling the function like this:
display_children(0, 0)
Each of the tiers is located in adjacent columns in a single table
tier1data, tier2data, tier 3 data……bustier1data, bustier2data…..
The array retrieves only the relevant tiers for this company and that is the
output of that array at the top of my example.
