There is this important rule that all programers must respect: write code YOU can understand. Khalil

DenesL, That works and just what I need. Thank you! Anthony, I did think that the first argument is the field to return :) Thank you for the clear explanation. Khalil, Thanks for the tips. I'd consider that for my projects.

Hi, This is why I almost never use shortcuts. When something goes wrong and you have poeple waiting for you to resolve the problem so they can get back to work, you always dont have enough attention to decrypt shortcuts. Khalil

It does not represent the name of the field you want to return. Anthony
