OpenCart Search & Product Options Not Working - Need a quick Fix - repost

Hello, I am having some problems on my open cart store. I know they will be an easy fix but I don't know what the problem is, someone who is more familiar with opencart and PHP would be able to figure this out very quickly. I am having a problem with my search bar, no matter which theme I am using and nomatter what I type into search bar, I receive 3 error messages about a problem in the [login to view URL] file. I need this fixed so that my search works properly. Also, I have a problem with product options. They do not show up as options on my products even after they've been added properly in the back end of my store. I need to have these options enabled so that people can place orders correctly on my store. This job is a flat rate, minimum payment job. I know it is an easy fix. $30 bids only, please. I also would like you to explain to me what the problem was, and what was fixed so that I can learn :)
