Sumproduct with Indirect

[SubhasisB]

Hello Friends,
I have two file, one file is having the companywise production, production cost, fule and power cost in different sheet and another file is the summary file with is a summary of company wise details, I am using sumproduct formula to fetch data in summary sheet.
My question is how can I use indirect function with sumproduct to fetch data from different sheets from the mainsheet file.
And also how can I automate row no D54 to D57 instead of putting formula manually in the summary file.
Please Help.
