Hi list, Hi Frank!

Thanks Steffen and Frank for your help!

I have remake my abstraction and I think now there is no mistake.
Now I want to create my array "$1_sample" dynamically, but message "array" doesn't work.
I receive "error: Bad arguments for message 'array' to object 'canvas'".
Any suggestion?

Saludos.
