Evaluation of a variable on the "right side" of a calculation (freeform text field)

Hi,

I was in the setup process of some calculations for an "if statement". Even tho you can select an existing variable (either a default or a user one) for the "left side" of a boolean comparison, inputing the name of a variable in the "right side" freeform text field does not cause the latter variable name to evaluate and return it's current value.

Is there a way to reference an existing variable in a calculation? I saw that the "Input text" action was featuring a name pattern in the likes of "(BTT)@variable:my_variable_name(BTT)", hovewer this does not evaluate in a calculation either.

Could you please light my lantern on this situation?

Best Regards,

Robert
