In the following calculation:
Nut_calcs::Std_EN = "No Std"; "No Std";
Nut_calcs::Std_PN = "No Std"; "No Std";
IF either of the Std's does = "No Std", it doesn't return "No Std", it just ignores it. No difference if I encapsulate the whole calc within Evaluate(Calc). NB. All the source and results fields are 'text'.
I'd be interested in the 'rule' governing this?
