n00b question - unique seed numbers

Hi all.

Although I have a fair amount of experience with the javascript-esque scipting in After Effects, I am pretty new to MAX Script, so please be gentle with me! ;)

Basically I am using Float Scripts as parameter controllers. In the scripts I want to have some code that seeds the random number to a unique number.

I have used he following:

seed thisIndex.handle //thisIndex being an assigned node to the object

... However, this only gives a unique number for the object and not for each individual parameter, which is what I am after.

If anyone can help or point me in the right direction for this I would be hugely grateful.

Thanks (and apologies if this post is a little unclear)

Jamie
