dynamically change value of expression parameter

[NikolajEgeskovOstergaard]

For the below variable setup  i wish to create an expression to dynamically get the values of the subcontainers.

- I tried something like :    value 1 = Evaluate("FileGlobals.MainContainer." + locals.currentSubContainer + ".value1")

How do i use evaluate to dynamically change which container is read ?

locals.currentSubContainer = "subContainer1"

... get value 1 

... get value 2

locals.currentSubContainer = "subContainer2"

... get value 1

... get value 2

FileGlobals

    "MainContainer"

        "SubContainer1"

            "Value1"

            "Value2"

        "SubContainer2"

            "Value1"

            "Value2"

Sounds like the property loader would be the best answer.....

I don't need to control it externally.

I just need to use same subsequence to do same thing multiple times using different settings.

The "setting" should be dynamically changed based on a parameter "A", "B", "C". ect.

Something like:

i just can't make it work.

Locals.currentFrequencies.F1 = Evaluate("fileglobals.CalibrationSettings." + parameters.currentFrequencySet + ".F1")

Gives me an error:

"A range is only valid inside an array subscript"

what does it mean, and why ?

Can you attach a small example of what you exactly tried?

Solved it.

TS apparently checks if the dynamic value "exists" in the Variable list.

The parameter  was "empty" in my list hence it didn't work. If I gives the subsequence parameter a "dummy" value that actually exists but overwrite this before real use, it works.
