Evaluating the field formulas before the column formulas is in general a bad
idea. Results of the field formulas will always be overwritten by the column
formulas (if there is a conflict).
Here you need to evaluate the spreadsheet twice to yield the intended result (I
get a 5 in field @2$3). From info:org:Updating the table:
