I need the following design: http://www.nemtechcs.com/merccom ported to work with xoops. I'm not xoops expert, and this is the first time I've ever used a cms system. So any and all help is appreciated!
dear raithedavion, welcome to xoops, this is not a free template, it's a design for a working website,and there is professional ethics and regulations adhered to by all designers to respect copyrights.
What did you get with your purchase? An index.html and a default.css file? Was it sold as a XOOPS theme?
You could try to copy eg the theme default in /themes/ to eg mercom Then merge the content of /themes/mercom/style.css with your style file and check the result after selecting this theme in the general preferences.
While it looks like a complete XOOPS site it is not. XOOPS is modular and all things are gathered togheter. Probably your monolithic files have to be broken up to the various composing blocks. Study the defauklt and zetagenesis themes.
