Need to add search function to existing DataAssist page
I've built a site using DataAssist and eCart, and it was extremely difficult. I'm just not a programmer. Now the client contacted me about putting in a search function. As I recall, creating the pages was pretty straightforward, but the eCart portion of the site required a considerable amount of help from the forum.
My question is this - Can I redo ONLY the pages of the site to add a search function, without having to redo or change the existing checkout?
Any help or suggestions would be greatly appreciated.
