hey i managed to remove things that I don't want on certain pages. it took me a long time than expected.

i tried layout box controller to turn off the left and right column on secondary pages (not homepage) for an example, product pages - it still shows two columns. Is there another way to turn them off?

I am not familiar with PHP or the way zencart is set. I am very newbie and it overwhelms me..

Question:
I am frustrated with having to find files that I need to edit products etc. I also don't understand what ez page does even though i read tutorial. I wanted to make some new templates in html code and I am wondering if it will override everything? If so, where should I put them? in common folder? how will zencart know that they are needed for the website?
