Can't search with Jquery .attr results

1

In the following code I define a variable, var panel by using the method .attr on an element. I get a result of var panel = “#panel4”, which I confirm by using an alert(). So far so good. BUT, when I put this variable inside a Jquery function so as to toggle an element which has an id=“panel4” as in:

$(panel).toggle();

^This does not work. If I change this code to:

$("#panel4").toggle();

it works!

Anyone know why I can’t use my variable in this code?
