macro written in Excel 2000 not working in Excel 2002
 

I have a macro that I wrote in Excel 2000 and when I try
to run it in Excel 2002, it brings up the debugger. The
message is:

'Compile error:

Wrong number of arguments or invalid property assignment'

What is highlighted is a call to Value(row, col),
specifically in Sheet1.Range(range).Value(row, col).

Any idea what's going on?
