Activating the third column for widgets
 

I am using a theme called soccer football theme 1.0 by elitethemes.net and it is stated as a 3 column theme. However in the third column I cannot change the widgets so only the search and archive widget are displayed. My domain is http://www.thatsagoal.com.
I want to alter the third column so I can add widgets for advertising as I have done with column one but I cannot find any answer as to how to do this.
Please Help!!!

Love to help, but this forum is for the 'Atahualpa' theme. I suggest you contact your theme's author.
