Creating value expression​s dynamicall​y with strings and numbers?

Question

Hello everybody!
I'm having a problem regarding passing arguments (DLL-Adapter) from different locations to a function in TestStand 3.5.
Here is what I have:
FileGlobals.Data.MyArray
and
StationGlobals.Data.MyArray
Which means there are 2 arrays of the same type, one stored in the sequence and one globally. "Data" is just a container.
The type of MyArray is a custom one each element containing a string and a number: Array[n].Name and Array[n].Nr
Now I want to pass (string) arguments of the array to a function using a value expression of: FileGlobals.Data.MyArray[Step.index].Name
Whereas Step.index is a local property (number) of a custom step. It's working well!
Here is the actual problem:
Since I have to sources, FileGlobals OR StationGlobals, I want to specify dynamically which string to pass.
Therefore I introduced a property Step.ThisIsMyScope . It's a string containing either "FileGlobals" or "StationGlobals".
I have been experimenting in expressions like
Step.ThisIsMyScope + ".Data.MyArray[" + Step.index + "].Name"
or Evaluate(...) , etc.
Nothing worked.
I do not want to use the API, though I managed to do things with getValString and temporary saving the Value in the step, but that's not nice nor transparent enough.
May anyone help me?
Thank you very much,
Stefan

Hi,
have you tried Evaluate(Step.ThisIsMyScope + ".Data.MyArray[" + Step.index + "].Name")
or
(Step.ThisIsMyScope == "FileGlobals"  )  ?  (FileGlobals.Data.MyArray[ Step.index].Name)  :  (StationsGlobals.Data.MyArray[ Step.index].Name)
