Why multi-state won't read a replacement value from a table lookup attribute?

Hi,

I have a PIVision display where I need to set multi-state to an attribute. The limits are set in AF using a table lookup, which searches the limits for each product in the mill.

However, some products don’t have @HiHi values, resulting in “No Data” being returned. This is problematic because the multi-state has @LoLo and @Maximum correctly, but @HiHi shows “No Data” in between them.

I’ve tried using the Replacement Value when constructing the table lookup so that when there is no @HiHi value available, it returns the @Target trait.

However, the replacement value doesn’t change the “No Data” value for @HiHi to @Target

It only works if I set a numeric static value, instead of a reference

Any help would be appreciated!

Thank you!
