Referencing .$REF of a dynamic reference

Hi is it possible to dynamically reference the .$REF field of another dynamic reference and then write a path through the first parameter?

i.e. DYN_PARAM1.$REF = "//MODULE/DYN_PARAM2.$REF" 

DYN_PARAM1.CV = "//MODULE/PARAM3.CV"

That is what I am trying to do but the second line does not seem to take. Is there another way of doing this? 

Thanks!

  Quyen, That's interesting. So in the example above, you are reading the path defined in $ref of DYN_PARAM2. THis would make both dynamic References point to the same parameter, whatever the text sting is in DYN_PARAM2.$REF
  
  So if DYN_PARAM2.$REF was set to //MODULE/PARAM3, then both DYN_PARAM1 and DYN_PARAM2 would be reading PARAM3.
  i.e if //MODULE/PARAM3.CV = 65.3
  then DYN_PARAM1.CV = 65.3 and DYN_PARAM2.CV = 65.3
  
  DYN_PARAM1 would not equal a string.

  In reply to Andre Dicaire:

  Thanks Andre, I will just set up my dynamic reference after I know the module with IF/THEN statements.

  You want to know:

  1. MODULE1 has a dynamic reference parameter DYN_PARAM1 where the $REF is setup to MODULE/PARAM3
  2. Another module named MODULE2 has a DYN_PARAM2 that is pointing to MODULE1/DYN_PARAM1
  3. You want to have logic in MODULE2 to change the $REF of the MODULE/DYN_PARAM1 using the local DYN_PARAM2 dynamic reference that is referencing the parameter

  Is that right?

  If that is what you are asking then the answer is NO because your logic would be something like '^/DYN_PARAM2.$REF' which would be changing the local reference and not the destination dynamic reference. You would have to use the format '//MODULE1/DYN_PARAM1.$REF'.

  Seems complicated to try to do this, what function or problem are you trying to solve with this type of configuration?
