Custom code help

[DerekM]

I want to add a custom code field at task level that would hold a value
between 1 an n, with no overlapping values to be chosen. So if I list 10
tasks only 1 task can have a value of 1 lets say. What type of expression do
I need here? Thanks

if its not static (ir can change happily) then reference the ID field
(or just use the id field). if you want it to be static then its
data-entry time (or write a macro to populate it).
