Accessing user defined properties from global macro

Is it possible to access user defined properties from a global macro?   I'm trying to change the Simulate Translation and want to define some behavior based on a user defined property.  I defined a property using two different types of "Name", one was the number 20000 and the other was "U:Format".  I've tried to access of these with the SrcStr.Property(<Name here>) and the result was empty.  Both of these variation work in a different non-global macros I've run.
