Hi,
I am making a perl module .
However , I am want to use another module support in my pm file subroutine .
The subroutine is as follows :
      sub xls_conv($)
      {
       use Spreadsheet::ParseExcel;
       my $oExcel = new Spreadsheet::ParseExcel;

       my $excelfileis = $self->{filename};
       my $oBook = $oExcel->Parse("$excelfileis");

for(my $iSheet=0; $iSheet < $oBook->{SheetCount}; $iSheet++)
       {
               print "$oBook->{SheetCount}";
       }

      }

However , when I use the above module subroutine in my perl script I get an error as :
Use of uninitialized value in numeric lt (<) at /usr/lib/perl5/site_pe
+rl/5.8.1/Converter.pm line 149.

Line 149 refers to the 
for(my $iSheet=0; $iSheet < $oBook->{SheetCount}; $iSheet++)

[download]
.
Can you suggest me what's going wrong in my subroutine .
