I am working in automation of a file in Excel and it requieres that I do adding for example add all numbers in column H so in excel I can do this = sum (H1:H30) so I try to duplicate the same in perl but is giving me an error message in the workbook. #żNOMBRE? and when you press F2 this is what it shows: =sum("H17:H.$Lastrow3") my excel is in spanish but I think is #NAME? in english this is a little example of the problem that I have:

#!/usr/perl/bin 
use Win32::OLE;
use Win32::OLE::Variant;
use Win32::OLE::Const 'Microsoft Excel';

my $LastRow = $Sheet->UsedRange->Find({What=>"*",

                  SearchDirection=>xlPrevious,
                  SearchOrder=>xlByColumns})->{Column};

####END OF PROBLEM################
