Sum values contained in record and multiply those values by the column's associated lookup

Hello everyone,

I'm not sure my title is the greatest for this problem, but I am unsure how to explain it in such a short sentence.

Basically, I would like to calculate the professional fees of certain roles, during certain phases of a project. In my sample file you will find two worksheets. The first Worksheet is Deliverables (this is the phases of the project) and the second Worksheet is Deliverable Summary (a summary of the fees associated with each phase (deliverable) of the project).

In the Deliverables worksheet, you will see that every Deliverable has a Tab Level of 1 in the column to the left of it. This is an indicator of phases. Between each tab level of 1, is a phase of the project. To the right of the Deliverable's you will find days worked by certain roles (Role 1, Role 2, Role 3, etc.) and their respective days worked under them. Please note that there are days worked in the Sub Deliverable and not the main Deliverable (the ones with a Tab Level of 1).

In the Deliverable Summary worksheet, you will see a table that I have summarized to the best of my ability.

Professional Services column is a list of all Phases in the Deliverables worksheet, to the right is the summation of the deliverable's Professional Days (Professional Days column). In the same worksheet you will find a table called Role's Daily Fee, this table contains the Role's fees.

I would like the professional fees column to calculate the total fees (Roles * Days) by Phase.

In the attached sample file, you can see my manual calculation in the Deliverable Summary worksheet - Professional Fees Column.

VBA or Worksheet Function?
If a formula isn't possible I would be okay with doing this via VBA Macro, but I'm not sure where to start there either! If this isn't clear, please don't hesitate to ask so that I may clarify.

Thank you very much,
