Yes, that is my aim, to modify existing scripts. It's finding some simple ones that has been the challenge. (I know Java is something else--and NOT coffee!--and hope not to tangle with that at all!)
Any suggestions on the search parameters to come up with those free scripts? Any favorite sites? Those are what I'm looking for, and I've viewed the source code on quite a few existing pages, but so much stuff gets tangled into these things and makes it a real puzzle. I've had some formal web design training, but haven't had time to take a JavaScript class yet. That makes this the seat-of-your-pants school of web design. I tried putting JavaScript into the FrontPage format and it hijacked it and messed it all up. I am pretty well stuck with Front Page because it is the default program from where I work, but I can simply paste something into the html view and save it to the server without too much interference.
(I suppose I could go view Mudcat's source code--they have some nice touches in here!)
