Calculated fields across stages

Is it possible to enable calculated fields across stages in a recipe? I’ve tried using unique tags, but it doesn’t seem to work. Could this be implemented?
Thanks in advance.

Hi Steve,

Calculated fields should work across stages, and be able to use tagged readings from any stage of the recipe. Usually the first thing to double-check if a calculated field hasn’t returned a value is to check whether one of the readings is missing - but if that’s not the case, if you could describe an example we can try and replicate it and have a look!
