0x800a138f - JavaScript runtime error: Unable to get property 'left' of undefined or null reference #72

I'm encountering the following error - 0x800a138f - JavaScript runtime error: Unable to get property 'left' of undefined or null reference - when trying to implement jquery.shapeshift on one of my websites.

It's occurring on this line of the javascript file

ui.position.left = e.pageX - $selected.parent().offset().left - selected_offset_x;

Has anyone encountered this error before?

This could be because you are using elements that have a larger colspan than the amount of columns available.

I wish I could give better support but I am trying to spend my time making 3.0 perfect rather than try to band-aid over the current 2.0 version. It's still TBD on the release date so sorry I can't offer any good news but I am not giving up on it and hopefully will have more free time available soon to update it.
