Sorry guys, I was silent for quite sometimes.... Today I'm on leave so I had a chance to log in here :)
Mike, My products are more than 3 level deep and so far it is working ok. I'm working on a copy function so that we can further sub categorize the parts/items that I have. As for your problem, I would like to suggest that you try it on a clean OSC. Please let me know the result.
Since I seldom log in to this forum, if you have any problem, you can email me directly azrin_aris at yahoo dot com. or msn at azrin dot aris at live dot com. I will try as much as I could....
