Loading Numeric Data from Text File for Numeric Limit Test

I'm a brand new TestStand 2014 user.  Just downloaded the demo, successfully ran the computer.dll tutorial & the "Loading Limits From a Text File.seq" example; & am now attempting to build my own sequence from scratch.  I want to load a number from a text file using Property Loader.  The file contains this:

GGbeg
484
GGend

My Main sequnce contains 2 steps (see attachment):

Property Loader (which reads the text file & should store the number 484 in the variable Step.Result.Numeric, right?)

GG-numeric-test (which should test the number 484 in Step.Result.Numeric as the Data Source, right?)

But when I execute it, the Measurement shows "0" for the value instead of "484".  What am I doing wrong?  Thanks in advance for your help!
