Widgets and url

I have a theme, iNove 1.4.6 by mg12 that has a widget I can use that is about 260 pixels wide. I want to be able to put to banners side by side in that widget. I can do that but when I add the url to each banner, it won’t save.

How do I change to he widget so that it will allow me to add two banners that are 125 x 125p wide, side by side and remain clickable to the intended url?
