Populate array with random, unique numbers

[Dave (David Wiebelhaus)]

Not exactly following the steps you wanted, but this way might be a better solution to get the same outcome you want.

I created an activity that receives a datatable as an in argument, randomizes it by performing a fisher-yates/knutes shuffle, and outputs the randomized datatable as an out argument.

This might be a better way to go about it as it can be used for many things. In your case, you’d simply pass in the table to be randomized, then grab ‘n’ rows, where n = number of selections required. It can be used in any other instance where randomization is needed. Re-useable code is always nice
