pick the corresponding Rate based on multiple selections and the term selected

Dear Forum Expert,

First of all thank you very much to give me the solution of my previous post using INDEX MATCH function.

Yet again, here is another table on which I am working but unfortunately I was unable to get it done.

On the updated sheet I need to pick the corresponding Rate based on multiple selections and the term selected. All the data is on one sheet called “GRID DATA”.

Here is the example of a selection and what should be the result:

Start Month: 15-AUG
Zone: Houston Zone
Profile: Low Load Profile
Term Entered: 24
Rate: 4.51₵
The rate should be average of 24 rows Starting from 15-August (based on the start month selected), in Column ‘Houston Zone’ (the Zone selected), for the profile ‘Low Load Profile’ (the profile selected).

Example 2:
Start Month: 15-OCT
Zone: Houston Zone
Profile: High Load Profile
Term Entered: 9
Rate: 3.88₵
The rate should be average of 9 rows Starting from 15-OCT (based on the start month selected), in Column ‘Houston Zone’ (the Zone selected), for the profile ‘High Load Profile’ (the profile selected).

Awaiting feedback. Thanks and Regards.
