Hi there, 

 

You can use an Excel script to do that - that would be the most efficient way.  Paul Murana walks through that here, in his "Array Reverse" script.

If you're not into that, this works too:

1. Create a new array (I called mine arrBackwards)
2. Use an "Apply to Each" and point it at your original collection.

3. Get the last item in the Forwards array:  last(variables('arrForwards'))

4. Add it to the Backwards array.

5. Remove the last item from the Forwards array. take(variables('arrForwards'),add(length(variables('arrForwards')),-1))
6. Set the Forwards array to the previous compose so we reference that going forward.

 

 

That did the trick.
