Hello, Can someone help me with the following problem?
I use this command to retrieve the devicecolumn of my excel sheet:

$devcolumn=getcolumn($sheets, 1,"/dev/disk*");


sub getcolumn    { 
    my ($sheet, $searchdir, $searchstr) = @_;
    $sheet = $Excel->Worksheets($sheet);
    my $LastCol = $sheet->UsedRange->Find({
        What=>$searchstr,
        LookAt=>2,
        LookIn=>-4123,
        MatchCase=>"False",
        SearchDirection=>$searchdir,
        SearchOrder=>xlByColumns})
      -{Column};
    return ${LastCol};

This works perfect.
But if there is no column with the earchstring "/dev/disk*" I get the following error:

Can't use an undefined value as a HASH reference at .....

I hope there is someone who deal with this problem before.

Greets,
Mieke
