phatfusion sortable expands my webpage-CAN'T FIX HELP

HELP.......please. I have a photo of before and after attached to show you what I'm talking about.

I have a web template that I'm using and when I go to insert the phatfusion sortable my page expands really wide and my header and overall page is all wrong. I have scoured the internet for a fix on this and how to stop the page from blowing out of bounds. I hope it's something simple and I'm sure it is but I'm really new at this so can anyone enlighten me on how to fix this? I'm wanting the sortable to list the football players where parents or whomever can find their player and this sortable is the best I have seen.

I have used this on a page that must be fixed in size and it works fine.

Here is my website so you can see how the page looks. Only News and Schedule is active right now.  http://alcoafootball.net

Thank you,

Jen
