EUREKA! works on OSX 10.4.11 now
In case this will help someone else, I discovered why my contact form page was not working on my older Mac with OSX 10.4.11
Apparently CSS Sculptor I used, creates an "@ import URL" to attach the CSS files, and while that worked on my newer Mac and most PCs I tested on, @importURL will only work in the "root" of the site but not when it's in a subfolder (and I had all the contact form solution pack files in a subfolder) when you are using OSX 10.4.11
So all I did to fix the problem was change how the external CSS files were linked, and now IT WORKS!!! I'm so relieved, because there are probably a lot of people out there who still use Mac OSX 10.4.11 because it really isn't that old of an operating system.
