Question about draggable with helper function in UI 1.5.3

Question about draggable with helper function in UI 1.5.3


Hi i'm for diffrent reasons still using jquery core 1.2.6 and UI 1.5.3
and at this moment not able to switch to the newest versions.
I have looked at the example code for making a draggable with helper
function on http://jqueryui.com/demos/draggable/#visual-feedback, this
is UI version 1.7.
The problem is that when i'm using the example code with my versions
of jquery i keep getting a "e is undefiend"-error for the draggable
with helper function. clone and original works fine thou. Has there
been a signature change or is it another problem?
i'm using the exact code from the example and have included my files
correctly(otherwise clone and original wouldn't work), how should that
code for helper function be written to work on jquery core 1.2.6 and
UI 1.5.3?
Many thanks!
