Storing element height in var via jquery

EDIT:

Here is the code exactly as it is in my file:

Relevant HTML:

<a href="javascript:void(0);" onmouseover="return overlib('Farewell - N.C. Hunter Hayden', HEIGHT, -1, WIDTH, -1, ABOVE);" onmouseout="return nd();" onclick="andherewego(1); setTimeout(function(){document.getElementById('farewell').play();},965);"><div id="note_1"></div></a>

Clicking this will call the function andherewego(p). Here is that function:

function andherewego(p){    // p is the # of the note pressed

initiatestafffade();    // set times for notes and notation to fade,
                        // and fades them
setTimeout(function(){
    changingoftheguard(p);  // show writing_p, paper, marginline,
                            // back_p
    hackemoff(p);           // re-define height for paper, marginline,
                            // back
    hidingfromjudgement(p); // determines how many covers to show and
                            // shows
                            // them
    nowheretohide(p);       // set times for covers to fade, and fades
                            //them

}, 950);

}

This function calls hackemoff(p), which I have put below:

function hackemoff(p){
var writingheight = $("writing_"+p).height();
alert(writingheight);
$("#paper").height(writingheight-300+50);
$("#marginline").height(writingheight+50);
$("#back_"+p).height(writingheight+50);

}

That is the code. If my syntax is indeed flawless, as you say, for the line

    var writingheight = $("writing_"+p).height();

then I do not understand why writingheight is null. I am grateful for you to be looking at this.

ORIGINAL POST:

I am trying to store the value of an element's height in a variable, so I can use it to set the height of other elements. My issue is with storing the height. I thought I could try this:

var writingheight = $("#writing_"+p).height;

(There are several div#writing_x elements.)

Why does this store a long mess in writingheight instead of the height value?

You need to execute it by (), or you are just assigning the jquery function to the variable.

var writingheight = $("#writing_"+p).height();
