Sub-values from a true position characteristic with PCM

[[Jo...]]

Hi All,

How do you pull the sub-values from a true position characteristic with PCM?

I have a true position of a Ø (-H-) to a datum scheme (-A-B-C-), and it reports the calculated value. I need to report the correction values for pulling the true position in spec. 

I know that you can enable an additional printout to get these values, but I would prefer to pull this into a standalone characteristic (Result element) using PCM.

 

When I attempt to cheat the software with "getActual("-H- Position1").y" I receive the following error. 

 

Any help is appreciated!
