Error on PHP file, not sure what to do

[timhersh]

I took over a wordpress website and thought everything was pretty simple. I downloaded all the files and uploaded it and everything worked great..until I realized there was a section on this site I wasn't aware of.

The site has a product section that lists all types of products. It is not working, nothing show up at all.

I researched it the best I could and discovered that if I navigate to a specific file on the website it gives me an error message. I'm thinking this might be the problem with why the site is not working. All I did was change the hosting company.

The main problem is that I am good with most tasks in PHP but this is involving XML and I am not sure how XML scripts work.

Here is the error:

Fatal error: Call to a member function getElementsByTagName() on a non-object in /home/image/public_html/indoorcomfortteam.com/wp-content/themes/indoorcomfortteam/inc/product-top.php on line 77

Here is the code for that file. line 77 says this
