ABC of arrays

Yep.  myArray[1] Can either have a value such as "cheese" OR it can hold
more boxes/parking spaces/whatever.  But there is no way to have myArray[1]
contain "cheese" AND more boxes.

so if your array has myArray[1][2][3] and you put "Cheddar" into myArray[1]
everything in myArray[1][2][3] goes away.  So its either a  value, or more

You can see this in action with a simple script like this:
put 1 into myArray[1][2][3]
put the keys of myArray[1] & " First key put" & cr -- puts key 2
put 1 into myArray[1]
put the keys of myArray[1]  & " Second key put" after msg -- puts no keys
because we wipe them out by putting a value in instead.
