Excel office need to get rid of warning windows

I am getting some warning windows as I am using "Copy Paste Link" function (see attached pdf). I cant remove the link as I then loose the the copy paste. I think that the fix is located on the "Info" page under "Trust Settings" (see attached), but there are so many options to go through. If someone could give me an idea where to look that would be great. In the meantime I will plug along searching each catagory.

Thank

Bill
