Hi, Aldebaran

I cannot thank you enough with your help.

I finally did a simpler version that is about 180 lines of code and posted it here: https://github.com/chungley2000/perlTKIssueSample/

I found a different solution to my problem which does not involve the use of "selectioncommand". Instead, when the "Get Files" button is clicked, I just used the $table->curselection() and resolved my solution then. I am still very interested in why the selectioncommand stopped working. According to the users, it was working before. But I cannot seems to "trigger" it. I tried to do a $table->get("0,0") to see if that is a "selection get" that the https://metacpan.org/pod/distribution/Tk-TableMatrix/pod/TableMatrix.pod was referring to, but that didn't do it.
