Multi-sit Script problems

I am relatively new to building and certainly to scripting, so I am hoping this problem is fairly simple to resolve. I have a multi-sit script that has worked for me before, but now it is showing an error. This error only shows to the owner of object that has the script in it. And even though it errors, the script itself still works just fine. The error appears (only to the owner) and then disappears after a minute. This is what the error says:

Script trying to stop animations but PERMISSION_TRIGGER_ANIMATION permission not set

Can anyone please help me with this? I would really appreciate any help I can get. I am at a loss with this.

Thanks!

Make sure the variable that holds the sitting AV's key is initially set to NULL_KEY and do an if (keyVar != NULL_KEY) check before any llStopAnimation() and llStartAnimation() calls. Just defining a key variable isn't enough, although logically you'd think a new variable would be set to NULL_KEY automatically. It isn't, as I found to my annoyance when working on an existing poseball script that assumed the same thing and would error in the exact same manner even with those checks in place until I explicitly initalized it with NULL_KEY.

Thank you for your response, Talon! Unfortunately this isn't the problem.....I'm beginning to wonder if it is a bug in my version of SL...? I bought a new multi-sit script and it is doing the same exact thing. I haven't touched the script itself, so I know it isn't anything I myself might have changed.....It is very odd. Everything should be working without an error, but it is still presenting the same error.....
