[Closed] Scipt Controller Error, Please help

Hi All …
While rigging a character, I am using script controllers (position) for 9 Helper Objects.
These scripts are almost the same on all the helpers. All these scripts have this line :

Rigd = (20 – $Teapot01.rigidity)

Now, the parameter ‘rigidity’ that you see above is a simple custom attribute of type integer that I added to this teapot.

Trouble is that the script controllers on all objects works without any problems as long as I dont close Max, or reset my scene. But when I load my scene again, I have these 10 thousand windows opening up and telling me :
>> MAXScript Script Controller Exception: – Unknown property: “Rigidity” in $Teapot:Teapot01 @ [56.894974,-28.709782,0.000000] <<

When I okay these windows and when I ‘evaluate and close’ the script windows that had popped up, everythings fine…
This script is really giving me good results but with these errors, I wont be able to network render …

Has anyone faced a similar error … any solutions? … please help
Another question :
Does Max remember which object was created first, which last? When loading a file, does it respect this order?

I hope I made my problem clear … if it didn’t make any sense, please say so, I’ll try to rephrase it…

Thanks, guys
