Thanks for the reply. optionmenu is a Tk widget.
I found that for Tkx, combobox is basically the same as optionmenu so I was able to use that.
I am continuing to have difficulties with the conversion. You suggested sticking with Tk, however, I don't have Tk included in the installation of Active Perl that I am now using. Is there a download you can point me to? Would it be a simple download of Tk to use my current script or is there more to it? Thank you again!
