How can I make one attribute of an object = an attribute of another object and vice versa so if I change on the other changes and if I change the other one the first one changes? when I try to do = one of them gets a connection and then I can't slide it at all while the other ones slides just find and controls both of the attributes I want to be able to click on either one to do that
The connection goes in only one direction. If it went both ways it would loop infinitely. You are better off making a null object, give it an attribute and feed its value into both your objects. Change it there and the others will follow.
