(Multimerch)USe Product title as Meta tile

I am runing a website on opencart 2.0.2.0 and usin template pavilion 1.2.5.
I also installed multimerch 7.1

link : http://greedam.com/index.php?route=prod ... uct_id=105

When i see the product url,the url is displayed as the html title.When i contacted the pavilion devs,their reply was
"You need to modify the INSERT/UPDATE SQL queries so and add the meta_title field that will get the product title ('name') field written into it. "

I am not a developer.kindly guide me the steps briefly plzz
