Hi, Pierrick.

You should change those INAA, INBB, and INCC fields, to just AA, BB, and
CC since they're just string values, not actual input links.

Also note that you will need the sCalcout record from calc 2-8 or newer
since there was a bug in calc 2-7 that would destroy a value in the BB,
CC, etc. fields in certain cases.
