Combining Sumproduct with indirect

Hi,

I have posted this previously but didnt get the required result:

HTML Code: 

so am trying again. I am sure i have seen this done but can not find it online.

I have 4 different data sheets:
Actual
Commitment
Q1 Forecast
Q2 Forecast


And I have a master sheet.

What I would like to do is have the master sheet pull data from the data sheets depending on what sheet has been selected on the Master sheet

e.g. On the Master sheet in cell G4 if this is “Actual” I would like it to return the numbers from the actual sheet.

I think I need an indirect/sumproduct formula. Can anyone help please?

I was previously helped but I do need it to include sumproduct and the ability to be able to drag the formula down and accross as my main dataset has 100+ rows
