Generally, what i am trying to create is a script that will make me 50 duplicates of my object, each object with his own random values as to scale, translate and rotation.

I wrote it this way that it'll make 10 copys of the object across the X axis using a loop,
I've put that loop inside another loop of which its objective is to repeat Loop-A 5 times, in which every time, it'll group all the objects in correct order and move them 45 units in the Z axis.

Though, for some reason, it refuses to work properly.
It says:
"Error: Not enough data was provided. The last 0 items will be skipped."
Though, The only time it does manges to work is when i ask Loop-B to execute only once instead of 5 times (Specificly, when i change the integer variable $zRows to 1).

I have attached the script,
Hope someone can help me on this one...
