problem running old maxscript file

[crz_06]

want to add some random bend value to my objects. For that i found this macxscript, which should run fine for version till max 6. However running it in max8 gives me an error, namely: Unable to convert: angle to type: float.

 

Any ideas how to fix this.

 

Maxscript can be found here > http://www.comet-cartoons.com/3dfiles/blowGrass.ms

 

other solutions are welcome as well. I want to bind a look at constraint to a bend modifier. In other words: The closer i come to an object the more it should bend. I don't want to animate this by hand, since i use a crowd system and have many object i need to bend
