oh ok. I think this is more of an Excel COM api question then, but I'll try and help.
You can get the value of a range using the Value property. If the range is a multi-cell range then the value will be a tuple of tuples, eg
value = range.Value[row][col]
The range object is also callable, returning another range, so you can also use:
value = range(row + 1, col + 1).Value
Note the +1s as Excel indices start from 1 not 0.
If you're doing something like this already and are getting that cannot use object as index error, I would double check the type of the index variable you're using to make sure it really is an int. Try doing a "print type(row)" and check it says <type 'int'>. Is it perhaps that you're using another range object and not the value of the range or something like that?
