This code should work, once you fix the creation of the vector: 20:-1:1.

Hello Rik,

Thx for your answer, I missed that one:-(

No problem. It's a very easy mistake to make. I don't make it daily anymore, but I still ofter forget :-1:.

Maybe I should get in the habit of using :1: for upwards arrays, that way you can't forget :-1: when you need it.
