Here I show you one of the procedures that I've created,.. here I'm trying to get the attributes of the nurbs surface (accesibility) in 2 points for each box. This will give them a sign (depending on where the accesibility is higher) and after they will move to the right or the left depending on their sign. (in the X direction)

The boxes are located one next to the other one (in the Z direction) and the value of the accesibility surface (in the Y direction).

In my script I would like to get the attributes of the accesibility in two different point of the X direction. $p should be the position of the box (and it is in the medium point of this one) and I would like to check the accessibility in -6 and +6 from this pont. The value that I should get then,.. It should be different because it's reading a surgace made of curves. But here comes the problem... when I print the values that it is getting,.. they are the same,.. So,. the program it's not reading the surface in a good way,.. and I can not figer out how to do it,.. :-(

I need your help,.. what is it wrong in the $l, and $r?
I should tell you that the surface of accesibility is a nurb with degree UV: 1

Here it goes a part of the script,... and if you need more,.. I can send it to you,...
thank you very much!!!!

pd. maybe it will be useful to know that: $p = getAttr ($name + ".translateX")
