Why doesn't this work?

@Value(SP)=FD?@Value(PCT):0

 

If the value of attribute SP is FD, then use the value of attribute PCT, otherwise 0. I tried using 'FD' and "FD" too.

Hi @mikek, in math expressions, you can operate only numeric values.

If you need to create a new attribute which could have one of two different values (@Value(PCD) or 0 in this case) depending on a condition whether an attribute value (@Value(SP)) is equal to a literal string 'FD', consider using conditional value setting in an AttributeCreator or an AttributeManager.
