Error for script when customizing out web page

Hello,

All I am trying to do is update our web ui by adding a new object to the homepage, but I am getting the below error when I check this and save:

Display this item on the home page
We have scripts in our URL string for a few of our Objects on the homepage that open a form.  I do not want these objects to break.  Any idea how I can do this without changing these scripts?
Thanks
Jeff
