If i have an input like so:

<input type=text id=textvalue />

the following code will change its value:

$(document).ready(function() {

    $('#textvalue').val(hello);

});

however the following will not work:

$(document).ready(function() {

    var = hello;

    $('#textvalue').val(var);

});

Why does the second one not work? I need to be able to change the value of the textbox to the value of a variable
