Issue Summary

We can only use the attributes belonging to variable inside the iterator and cannot use smart variables (created outside the iterator).

Steps to Reproduce

1. Create a variable in main branch
2. Add advanced Branching to iterate over another smart variable or use nested iterator.
3. Use the variable created in step one inside the iterator loop

Expected Results

We should be able to use it

Actual Results

We get error.

Workaround

No workaround for now.
