I have an array formula such as ...
={ ... *($G$98:$AZ$98)}

The formula references data found in row 98 of the worksheet.

Instead of typing the row number into the formula, I'd like to be able to
refer to a row number that I enter in another cell. For example, if I type
the number 74 into cell A1, I'd like the array formula to reference the value
shown in cell A1 such that the array formula is the equivalent of ...

={ ... *($G$74:$AZ$74)}

I use the array formula to create a multi-dimensional data table that I use
for charting. The same formula may be used hundreds of times when creating
the table. I'd like to be able to pull in data stored in any row that I
choose to plot.

I hope I am presenting my case clearly,

Thanks for any help provided.
