Tkx::Merge and text widgets

Good Day,

First, I am using ACTIVESTATE PERL 5.14 and Tkx.
I wanted to merge a list from a SplitList for example

my @goofy - Tkx::Splitlist($somestring);
my $newgoofylist = Tkx::Merge(@goofy);

but I key getting the following message:

invalid command name "Merge" at C:\qa\grunge.pl line 165.

invalid command name "Merge"
    while executing
"Merge 6.48 6.54"
    invoked from within
"::perl::CODE(0x3af961c)"
    (menu invoke)

What am I doing wrong???

Second question... again using the same PERL, is it possible to have the text widget do multiple selects?

thanks,
gary
