I'm trying to figure out how to have a certain value selected in a popup window show up in a text box in another window. Basically, if I were to click a link on this page a new window would appear with, lets say, a list of colors, each with a checkbox or radio button next to each color. If i select "blue" in the popup window, I'd like "blue" to show up in a text field in the original window. Can all this be accomplished with Perl, or would I have to implement some JavaScript?
