However.. this doesn't actually seem to solve everything im trying to do.
I can SHOW a computation. but i cannot submit a computation.
Here's what I want to do.
I want ColumnA to be entered at article creation, which is simply a number.
I want to Use a field LATER to ADD to ColumnA
So later, when I goto the form, I can see ColumnA is filled out with a number of 10. Type a '6' in the field to ADD to ColumnA, and when all is said and done. ColumnA is now a '16'
