Thanks for the info Nabiul!
The second question deals with the fact that the first element in an enumeration is 0. So if you get the number of entries in the enumeration, in a way it’s 1 too large for some functions. I am feeding this number into a random number picker and if it picks the max value (i.e. lets say 4 as in my above name example) it’s going to generate a “MAX EN” error message since the elements are 0-John,1-Terry,2-Chuck,3-Dave. It’s the same way that you have a LENGTH and LAST INDEX function with arrays.
