Hi,
Thanks for the suggestion, I can see how this would be really useful. We'll add it to the wishlist. In the meantime here's a little code snippet you can quickly use with the Arithmetic operator. I'm afraid it's using the nested If statements you mention but you don't need more that 20 inputs you can just copy and paste this expression:
if(Input1=1,Input2,
if(Input1=2,Input3,
if(Input1=3,Input4,
if(Input1=4,Input5,
if(Input1=5,Input6,
if(Input1=6,Input7,
if(Input1=7,Input8,
if(Input1=8,Input9,
if(Input1=9,Input10,
if(Input1=10,Input11,0
))))))))))
Many thanks!
Paul
